## Whats new This PR introduces some changes that improve the development experience via VSCode's devcontainers. Specifically: * It removes the cloning of the pandas repo inside the container (it assumes that the user already cloned it on the host) and instead leverages the fact the the code is mounted to `/workspaces/pandas`. * Defines the conda env inside the workspace itself such that it can be reused even when the container is deleted. This enables you to use the codebase outside the repo afterwards if you activate the same local conda env. * Splits the previous `Dockerfile` in two: a simplified `Dockerfile` + a new `container_create.sh` that only runs the first time the container starts, making it possible to install the dependencies inside the workspace.

Follow up to #36893. Per @xhochy's suggestion we should use `entrypoints` as a mechanism for loading alternate SQL engine backends, similar to what we do with plotting backends. Creating a new issue for it per the comment [here](https://github.com/pandas-dev/pandas/pull/40556#discussion_r625243915).

Not sure why a README was created under `docs` in the first place. But having a docs/README that instead of having docs related information, just points to the contributing page, doesn't seem very useful, since the main README is already providing better information on how to contribute. And in any case, the link in that README file is very old.

xref #41050 Feels like https://github.com/pandas-docs/pandas-docs-travis was created to publish the development pandas docs, but that was eventually moved elsewhere, and now there is just a two year old copy published there (in their github pages). I think we should delete the `pandas-docs` organization, to avoid confusion, or people accessing old docs from outdated links to that copy.

xref #33971 This used to run in Travis, but seems like Travis now requires credits, and we can't get them reliably (see #38943). [This page](https://developer.arm.com/solutions/infrastructure/developer-resources/ci-cd) contains CI systems that support ARM. Most of them require to set up our own runner, which I guess we don't want to do or maintain. So, the main options seem to be: - drone.io - CircleCI CC: @bashtage

- [x ] I have checked that this issue has not already been reported. - [x ] I have confirmed this bug exists on the latest version of pandas. - [ ] (optional) I have confirmed this bug exists on the master branch of pandas. --- #### Code Sample, a copy-pastable example ```python import pandas as pd ts = 1618556707013635762 pdf = pd.DataFrame([{"id": 2, "ts": ts}, {"id": 2, "ts": ts+1}]) pdf["ts"] = pd.array(pdf["ts"], dtype="Int64") pdf.groupby("id").agg({"ts": "min"}) ``` #### Problem description The above code will output `1618556707013635840` as the minimum which is incorrect. #### Expected Output Minimum should be `1618556707013635762`. I suspect there is a cast happening somewhere during the aggregation. If we keep the `ts` column at `int64` (i.e. use the non-nullable type) the result is as expected. #### Output of ``pd.show_versions()`` <details> INSTALLED VERSIONS ------------------ commit : 2cb96529396d93b46abab7bbc73a208e708c642e python : 3.9.5.final.0 python-bits : 64 OS : Linux OS-release : 5.11.7-200.fc33.x86_64 Version : #1 SMP Wed Mar 17 18:55:20 UTC 2021 machine : x86_64 processor : x86_64 byteorder : little LC_ALL : LANG : en_US.UTF-8 LOCALE : en_US.UTF-8 pandas : 1.2.4 numpy : 1.20.3 pytz : 2021.1 dateutil : 2.8.1 pip : 21.1.1 setuptools : 56.0.0 Cython : None pytest : None hypothesis : None sphinx : None blosc : None feather : None xlsxwriter : None lxml.etree : None html5lib : None pymysql : None psycopg2 : None jinja2 : None IPython : 7.24.0 pandas_datareader: None bs4 : None bottleneck : None fsspec : None fastparquet : None gcsfs : None matplotlib : None numexpr : None odfpy : None openpyxl : None pandas_gbq : None pyarrow : None pyxlsb : None s3fs : None scipy : None sqlalchemy : None tables : None tabulate : None xarray : None xlrd : None xlwt : None numba : None </details> #### Potentially related issues The issues below seem related, but from what I can see are slightly different: * https://github.com/pandas-dev/pandas/issues/37494 seems like a more general problem where it is a priori unclear what the resulting `dtype` of the output column should be. For the `min` and `max` I would expect to get the same `dtype` as in the input column. * https://github.com/pandas-dev/pandas/issues/41137 For the present issue we actually want to keep the original precision and not cast to float.

The DateOffset duplication is discussed in #41586. docbuild is segfaulting locally (independent of this PR), so will have to see if this works on the CI.

Admittedly this is extremely minor, but it's something that has always irked me. Currently for minor (single-line, not a section) enhancements and bug-fixes, we have the format: > This is sentence one (GH28527) which on its own is perfectly fine. However when a line has multiple sentences: > This is sentence one. This is sentence two (GH28527) the lack of a period at the end looks off to me. I'd prefer if we did full sentences for each line followed by the GH link at the end, this way a multi-sentence doesn't look so odd. > This is sentence one. (GH28527) > This is sentence one. This is sentence two. (GH28527) Another option is to limit one-line notes to being a single sentence (which I'm opposed to), and of course we could just stay with it as is. If we are to make any changes, I'd do it for the version minor/major version after 1.3.0. cc @simonjayhawkins

We'll start running ARM tests in #41739. In order to see the result of the execution in that PR, we need `.circleci/config.yml` to exist in master, so CircleCI starts showing in GitHub. Adding the config file, but just doing an echo (and not the checkout, set up or the environment or the running of the tests). So we can add CircleCI safely, and see results before merging #41739.

In #41160 , a new pyupgrade feature did some rewrites likes ```diff - s = "\n".join([_build_option_description(k) for k in keys]) + s = "\n".join(_build_option_description(k) for k in keys) ``` However, they then reverted this feature as it was a potential performance regression (https://github.com/asottile/pyupgrade/issues/456). I think we should revert those changes (though arguably not the entire PR) and add a rule to pandas-dev-flaker about using list comprehensions rather than generators when joining strings If nobody takes this on earlier, I'll do this on Friday

I post this as a "Question" because I am quite new to `pandas`. So maybe I miss some understandings and the "problem" described by me is by design and you have good reasons for that. I use pandas 1.2.4, with Python 3.9.4 on Windows 10 64 bit. As a user I would expect that pandas check the number of fields per row when importing via csv file. But IMHO it does not in all cases. # Example 1 Here is a csv file __without header__ and but a set `names=` attribute with three fields. So pandas should be able to know how many fields/columns should be in the CSV file. The second row contains 4 instead of 3 fields. ``` import pandas import io csv_without_header = io.StringIO( 'A;B;C\n' 'D;E;X;Y\n' 'F;G;H' ) df = pandas.read_csv(csv_without_header, encoding='utf-8', sep=';', header=None, names=['First', 'Second', 'Third']) ``` Pandas import this without warnrings or errors. The 4th field in the 2nd row is simply ignored. # Example 2 I added a header line into the csv file with again three fields. So pandas should be able to know how many fields/columns should be in the CSV file. And again the second row contains 4 instead of 3 fields. ``` csv_with_header = io.StringIO( 'First;Second;Third\n' 'A;B;C\n' 'D;E;X;Y\n' 'F;G;H' ) df = pandas.read_csv(csv_with_header, encoding='utf-8', sep=';') ``` Here an error occurs as I expect. `pandas.errors.ParserError: Error tokenizing data. C error: Expected 3 fields in line 3, saw 4` # Example 3 There are less then 3 fields in the 2nd row. Again here is no warning or error. The missing field is set with `NaN`. And here it does not matter if you give the number of (expected) fields via header line in the CSV or via `names=` attribute. ``` csv_with_header = io.StringIO( 'First;Second;Third\n' 'A;B;C\n' 'D;Y\n' 'F;G;H' ) csv_without_header = io.StringIO( 'A;B;C\n' 'D;Y\n' 'F;G;H' ) df_a = pandas.read_csv(csv_with_header, encoding='utf-8', sep=';') df_b = pandas.read_csv(csv_without_header, encoding='utf-8', sep=';', names=['First', 'Second', 'Third']) ``` Want I want is to import CSV files and be informed if there are to many or less then the expected number of fields in any row.

- [x] I have checked that this issue has not already been reported. - [x] I have confirmed this bug exists on the latest version of pandas. - [x] (optional) I have confirmed this bug exists on the master branch of pandas. --- #### Code Sample, a copy-pastable example ```python import pandas as pd # DateIndex containing only two values -- too few to infer a frequency from too_short = pd.date_range(datetime(2021, 6, 1, 0), datetime(2021, 6, 1, 1), freq="1H") # raises ValueError, as expected pd.infer_freq(not_too_short, warn=False) # also raises ValueError, not as expected pd.infer_freq(not_too_short, warn=True) # (this is the default arg for warn) ``` #### Problem description The [documentation currently suggests](https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.infer_freq.html) that, by default, `pd.infer_freq()` will warn when it can't infer a frequency (in this case because the range does not have at least three values). Instead it always raises, regardless of whether the `warn` parameter is set to `True` or `False`. Looking at [the implementation of `pd.infer_freq()`](https://github.com/pandas-dev/pandas/blob/v1.2.4/pandas/tseries/frequencies.py#L120-L183), the class that "does the work" is [`_FrequencyInferer`](https://github.com/pandas-dev/pandas/blob/v1.2.4/pandas/tseries/frequencies.py#L186). This class [sets `self.warn` in its `__init__()`](https://github.com/pandas-dev/pandas/blob/v1.2.4/pandas/tseries/frequencies.py#L203) but then never references it again. So it looks like the `warn` parameter is a dud. #### Expected Output I'd expect this line to warn instead of raising a `ValueError`: ``` pd.infer_freq(not_too_short, warn=True) # (this is the default arg for warn) ``` Since lots of code probably implicitly relies on the current implementation of always raising, it may be best to just remove the `warn` argument altogether, or document that it doesn't do anything. #### Output of ``pd.show_versions()`` <details> ``` INSTALLED VERSIONS ------------------ commit : 2cb96529396d93b46abab7bbc73a208e708c642e python : 3.9.1.final.0 python-bits : 64 OS : Darwin OS-release : 20.3.0 Version : Darwin Kernel Version 20.3.0: Thu Jan 21 00:07:06 PST 2021; root:xnu-7195.81.3~1/RELEASE_X86_64 machine : x86_64 processor : i386 byteorder : little LC_ALL : None LANG : None LOCALE : en_US.UTF-8 pandas : 1.2.4 numpy : 1.20.0 pytz : 2021.1 dateutil : 2.8.1 pip : 20.2.3 setuptools : 49.2.1 Cython : 0.29.22 pytest : 6.2.3 hypothesis : None sphinx : None blosc : None feather : None xlsxwriter : None lxml.etree : 4.6.3 html5lib : None pymysql : None psycopg2 : None jinja2 : 2.11.3 IPython : 7.20.0 pandas_datareader: None bs4 : 4.9.3 bottleneck : 1.3.2 fsspec : 0.8.7 fastparquet : None gcsfs : 0.7.2 matplotlib : 3.3.4 numexpr : None odfpy : None openpyxl : None pandas_gbq : None pyarrow : 4.0.0 pyxlsb : None s3fs : None scipy : 1.6.0 sqlalchemy : None tables : None tabulate : None xarray : 0.17.0 xlrd : None xlwt : None numba : None ``` </details>

- [x] I have checked that this issue has not already been reported. - [x] I have confirmed this bug exists on the latest version of pandas. - [ ] (optional) I have confirmed this bug exists on the master branch of pandas. --- #### Code Sample ```python >>> import pandas as pd >>> import numpy as np >>> np.mean(pd.DataFrame([[1,2,3],[4,5,6]]), axis=1) 0 2.0 1 5.0 dtype: float64 >>> np.median(pd.DataFrame([[1,2,3],[4,5,6]]), axis=1) array([2., 5.]) ``` #### Problem description The return type when applying `numpy` ops to data frames should be consistent. In this example, `np.mean` returns a `pd.Series` while `np.median` returns an `np.ndarray`. Code that applies dynamically selected numpy operations to pandas dataframes is likely to run into errors if the type of object returned is inconsistent, e.g. expecting to find an index and not finding one in the case of `np.median` #### Expected Output Both should be `pd.Series`. #### Output of ``pd.show_versions()`` <details> INSTALLED VERSIONS ------------------ commit : 2cb96529396d93b46abab7bbc73a208e708c642e python : 3.8.5.final.0 python-bits : 64 OS : Darwin OS-release : 20.5.0 Version : Darwin Kernel Version 20.5.0: Sat May 8 05:10:33 PDT 2021; root:xnu-7195.121.3~9/RELEASE_X86_64 machine : x86_64 processor : i386 byteorder : little LC_ALL : None LANG : en_US.UTF-8 LOCALE : en_US.UTF-8 pandas : 1.2.4 numpy : 1.20.1 pytz : 2020.1 dateutil : 2.8.1 pip : 20.2.2 setuptools : 49.6.0.post20200814 Cython : None pytest : 6.0.2 hypothesis : None sphinx : None blosc : None feather : None xlsxwriter : None lxml.etree : None html5lib : None pymysql : None psycopg2 : None jinja2 : 2.11.2 IPython : 7.16.1 pandas_datareader: None bs4 : None bottleneck : None fsspec : 0.8.3 fastparquet : None gcsfs : None matplotlib : 3.4.2 numexpr : None odfpy : None openpyxl : None pandas_gbq : None pyarrow : None pyxlsb : None s3fs : None scipy : 1.5.2 sqlalchemy : None tables : None tabulate : 0.8.7 xarray : None xlrd : None xlwt : None numba : 0.52.0 </details>

- [X] I have checked that this issue has not already been reported. - [X] I have confirmed this bug exists on the latest version of pandas. - [ ] (optional) I have confirmed this bug exists on the master branch of pandas. --- **Note**: Please read [this guide](https://matthewrocklin.com/blog/work/2018/02/28/minimal-bug-reports) detailing how to provide the necessary information for us to reproduce your bug. #### Code Sample, a copy-pastable example ```python import pandas as pd df = pd.DataFrame({"name": ["A", "A", "A", "B"], "value": [10, 20, 30, 10]}) df.set_index("name", drop=True).to_dict("dict") ``` #### Problem description This creates output: > `{'value': {'A': 30, 'B': 10}}` Which does seem odd. My expectation from pandas is instead of giving bare `30` and `10` as value to give a **list** of values. This only looks like a limitation to what pandas is able to do. #### Expected Output > `{'value': {'A': [10, 20, 30], 'B': 10}}` #### Output of ``pd.show_versions()`` <details> INSTALLED VERSIONS ------------------ commit : b5958ee1999e9aead1938c0bba2b674378807b3d python : 3.7.10.final.0 python-bits : 64 OS : Linux OS-release : 5.4.109+ Version : #1 SMP Tue Apr 20 19:55:43 PDT 2021 machine : x86_64 processor : x86_64 byteorder : little LC_ALL : None LANG : en_US.UTF-8 LOCALE : en_US.UTF-8 pandas : 1.1.5 numpy : 1.19.5 pytz : 2018.9 dateutil : 2.8.1 pip : 19.3.1 setuptools : 56.1.0 Cython : 0.29.23 pytest : 3.6.4 hypothesis : None sphinx : 1.8.5 blosc : None feather : 0.4.1 xlsxwriter : None lxml.etree : 4.2.6 html5lib : 1.0.1 pymysql : None psycopg2 : 2.7.6.1 (dt dec pq3 ext lo64) jinja2 : 2.11.3 IPython : 5.5.0 pandas_datareader: 0.9.0 bs4 : 4.6.3 bottleneck : 1.3.2 fsspec : None fastparquet : None gcsfs : None matplotlib : 3.2.2 numexpr : 2.7.3 odfpy : None openpyxl : 2.5.9 pandas_gbq : 0.13.3 pyarrow : 3.0.0 pytables : None pyxlsb : None s3fs : None scipy : 1.4.1 sqlalchemy : 1.4.15 tables : 3.4.4 tabulate : 0.8.9 xarray : 0.18.2 xlrd : 1.1.0 xlwt : 1.3.0 numba : 0.51.2 </details>

#### Is your feature request related to a problem? well sort of, currently one can not groupby on a column containing unhashable types (e.g dicts) #### Describe the solution you'd like an easy workaround is to groupby on that column as type str and then remap the strings back to their orig type, wondering if we can provide this process built in so one can groupby on unhashable types if she desires to #### Describe alternatives you've considered add a try except to allow hash(str(x)) in case hash(x) is impossible, or convert the column to str and add it back later ```python # Your code here, if applicable ```

I believe a bug was introduced in the update of `xs` in pandas 1.2.0. The problem occurs when requesting multiple keys in combination with `drop_level=False`. I use the following code to highlight the problem I face: ```python import pandas as pd d = [[4, 4, 2, 2, 8], [0, 0, 2, 2, 0]] tuples = [('mammal', 'cat'), ('mammal', 'dog'), ('bird', 'penguin'), ('bird', 'pidgeon'), ('insect', 'spider')] columns = pd.MultiIndex.from_tuples(tuples) df = pd.DataFrame(data=d, columns=columns, index=['num_legs', 'num_wings']) print(df.xs(['mammal', 'bird'], drop_level=False, axis=1)) ``` In pandas 1.1.5, the following output is generated (as expected): ``` mammal bird cat dog penguin pidgeon num_legs 4 4 2 2 num_wings 0 0 2 2 ``` While in pandas 1.2.4, an exception is raised: ``` Traceback (most recent call last): File "C:\python\miniconda3\envs\pandas_12\lib\site-packages\pandas\core\indexes\base.py", line 3080, in get_loc return self._engine.get_loc(casted_key) File "pandas\_libs\index.pyx", line 70, in pandas._libs.index.IndexEngine.get_loc File "pandas\_libs\index.pyx", line 101, in pandas._libs.index.IndexEngine.get_loc File "pandas\_libs\hashtable_class_helper.pxi", line 4554, in pandas._libs.hashtable.PyObjectHashTable.get_item File "pandas\_libs\hashtable_class_helper.pxi", line 4562, in pandas._libs.hashtable.PyObjectHashTable.get_item KeyError: 'bird' The above exception was the direct cause of the following exception: Traceback (most recent call last): File "pandas\_libs\index.pyx", line 705, in pandas._libs.index.BaseMultiIndexCodesEngine.get_loc File "C:\python\miniconda3\envs\pandas_12\lib\site-packages\pandas\core\indexes\base.py", line 3082, in get_loc raise KeyError(key) from err KeyError: 'bird' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "C:\python\miniconda3\envs\pandas_12\lib\site-packages\pandas\core\indexes\multi.py", line 3036, in _get_loc_level return (self._engine.get_loc(key), None) File "pandas\_libs\index.pyx", line 708, in pandas._libs.index.BaseMultiIndexCodesEngine.get_loc KeyError: ('mammal', 'bird') The above exception was the direct cause of the following exception: Traceback (most recent call last): File "C:\Users\jimzw\AppData\Roaming\JetBrains\PyCharmCE2021.1\scratches\scratch_4.py", line 9, in <module> print(df.xs(['mammal', 'bird'], drop_level=False, axis=1)) File "C:\python\miniconda3\envs\pandas_12\lib\site-packages\pandas\core\generic.py", line 3733, in xs loc, new_index = index._get_loc_level( File "C:\python\miniconda3\envs\pandas_12\lib\site-packages\pandas\core\indexes\multi.py", line 3038, in _get_loc_level raise KeyError(key) from e KeyError: ('mammal', 'bird') ```

- [x] I have checked that this issue has not already been reported. - [x] I have confirmed this bug exists on the latest version of pandas. - [ ] (optional) I have confirmed this bug exists on the master branch of pandas. --- ```python >>> import pandas as pd >>> import numpy as np >>> df = pd.DataFrame({'c1':[[1,2,3]], 'c2':[np.nan]}) >>> df c1 c2 0 [1, 2, 3] NaN >>> df.c1 + df.c2 0 NaN dtype: object >>> [1, 2, 3] + np.nan Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: can only concatenate list (not "float") to list ``` #### Problem description In Pandas when using the "+" operator on a Series entry containing a list and a Series entry containing a NaN value, a NaN value is returned. This is inconsistent with standard Python where attempting to concatenate a list and a NaN raises a TypeError. In general, list concatenation between a NaN and a list is an ambiguous operation and therefore should raise an error. #### Expected Output A TypeError should be raised. #### Output of ``pd.show_versions()`` <details> INSTALLED VERSIONS ------------------ commit : 2cb96529396d93b46abab7bbc73a208e708c642e python : 3.7.4.final.0 python-bits : 64 OS : Windows OS-release : 10 Version : 10.0.18362 machine : AMD64 processor : Intel64 Family 6 Model 142 Stepping 10, GenuineIntel byteorder : little LC_ALL : None LANG : None LOCALE : None.None pandas : 1.2.4 numpy : 1.19.5 pytz : 2021.1 dateutil : 2.8.1 pip : 21.1.1 setuptools : 52.0.0.post20210125 Cython : None pytest : None hypothesis : None sphinx : 4.0.1 blosc : None feather : None xlsxwriter : 1.2.8 lxml.etree : 4.5.0 html5lib : None pymysql : None psycopg2 : None jinja2 : 3.0.0 IPython : 7.16.1 pandas_datareader: None bs4 : 4.8.0 bottleneck : None fsspec : None fastparquet : None gcsfs : None matplotlib : 3.3.4 numexpr : None odfpy : None openpyxl : 3.0.1 pandas_gbq : None pyarrow : 0.17.1 pyxlsb : None s3fs : None scipy : 1.6.2 sqlalchemy : None tables : None tabulate : None xarray : None xlrd : 1.2.0 xlwt : None numba : None </details>

- [X] I have checked that this issue has not already been reported. - [X] I have confirmed this bug exists on the latest version of pandas. #### Code Sample ```python import pandas as pd import numpy as np df = pd.DataFrame([[1, 2, 3], [4, 5, 6], [7, 8, 9], [np.nan, np.nan, np.nan]], columns=['A', 'B', 'C']) print(df.agg(x=('A', max), y=('B', 'min'), z=('C', np.mean))) # Works fine print(df.agg(x=('A', max), y=('B', 'min'), z=('C', lambda x: np.mean(x)))) # Does not work ``` #### Problem description Passing lambda or user defined function causes `pd.DataFrame.agg` to crash. ``` Traceback (most recent call last): File "/home/tobii.intra/jzn/.PyCharm2018.3/config/scratches/scratch_200.py", line 22, in <module> print(df.agg(x=('A', max), y=('B', 'min'), z=('C', lambda x: np.mean(x)))) File "/home/tobii.intra/jzn/.virtualenvs/venv/lib/python3.7/site-packages/pandas/core/frame.py", line 7379, in aggregate result_in_dict = relabel_result(result, func, columns, order) File "/home/tobii.intra/jzn/.virtualenvs/venv/lib/python3.7/site-packages/pandas/core/aggregation.py", line 342, in relabel_result s = s[col_idx_order] File "/home/tobii.intra/jzn/.virtualenvs/venv/lib/python3.7/site-packages/pandas/core/frame.py", line 2912, in __getitem__ indexer = self.loc._get_listlike_indexer(key, axis=1, raise_missing=True)[1] File "/home/tobii.intra/jzn/.virtualenvs/venv/lib/python3.7/site-packages/pandas/core/indexing.py", line 1254, in _get_listlike_indexer self._validate_read_indexer(keyarr, indexer, axis, raise_missing=raise_missing) File "/home/tobii.intra/jzn/.virtualenvs/venv/lib/python3.7/site-packages/pandas/core/indexing.py", line 1298, in _validate_read_indexer raise KeyError(f"None of [{key}] are in the [{axis_name}]") KeyError: "None of [Int64Index([0], dtype='int64')] are in the [columns]" ``` When setting a break point in the user defined function I noticed that the input is not a `Series` containing all values of the column, but a single scalar value from that column. This seems to be isolated to `DataFrame.agg`, since my workaround was to add a trivial group by and make use of `GroupBy.agg`, which works fine. #### Output of ``pd.show_versions()`` <details> INSTALLED VERSIONS ------------------ commit : b5958ee1999e9aead1938c0bba2b674378807b3d python : 3.7.10.final.0 python-bits : 64 OS : Linux OS-release : 4.15.0-143-generic Version : #147-Ubuntu SMP Wed Apr 14 16:10:11 UTC 2021 machine : x86_64 processor : x86_64 byteorder : little LC_ALL : None LANG : en_US.UTF-8 LOCALE : en_US.UTF-8 pandas : 1.1.5 numpy : 1.18.2 pytz : 2020.4 dateutil : 2.8.1 pip : 21.1.2 setuptools : 54.2.0 Cython : 0.29.21 pytest : None hypothesis : None sphinx : 3.1.2 blosc : None feather : None xlsxwriter : None lxml.etree : 4.6.2 html5lib : None pymysql : None psycopg2 : None jinja2 : 2.10.3 IPython : None pandas_datareader: None bs4 : None bottleneck : None fsspec : None fastparquet : None gcsfs : None matplotlib : 3.3.4 numexpr : None odfpy : None openpyxl : None pandas_gbq : None pyarrow : 0.17.0 pytables : None pyxlsb : None s3fs : None scipy : 1.4.0 sqlalchemy : None tables : None tabulate : None xarray : None xlrd : None xlwt : None numba : None </details>

This is the `Index.union` part of #41153. This helps simplify that PR. The special casing in `Index.union` is currently active if both are numeric. After #41153 it should only be special cased if one dtype is uint64 and other a signed int. So after this and #41153: * int8 & uint32 -> int64 * [u]int64 & float64 -> float64 * int64 & uint64 -> object * int8 & uint64 -> object The first and second case is handled correctly by `find_common_type`, but the others aren't currently. This PR changes no functionality itself, but prepares for the changes in #41153, where we want e.g. `NumericIndex[uint8] .union(NumericIndex[int32])` to give `NumericIndex[int64]` and not `Index[object]`.

Kindly refer the following code snippet. `import pandas as pd` `import os` `# Creating a corrupted file` `with open('a.xlsx', 'w') as f:` ` pass` `# Reading using pd.ExcelFile` `data = pd.ExcelFile('a.xlsx', engine='openpyxl')` `# Deleting the file` `os.remove('a.xlsx')` Here, I create a .xlsx file which is not the correct way to make xlsx file but this will express my concern. Then I use pd.ExcelFile to read the xlsx file but it gives me `zipfile.BadZipFile: File is not a zip file` which is fine but later when I try to delete that file I get `PermissionError: [WinError 32] The process cannot access the file because it is being used by another process: 'a.xlsx'`. This doesn't happen in `pandas==1.2.1` and lower version. The current version i.e. `pandas==1.2.4` has this bug.

- [x] I have checked that this issue has not already been reported. - [x] I have confirmed this bug exists on the latest version of pandas. - [ ] (optional) I have confirmed this bug exists on the master branch of pandas. --- #### Code Sample, a copy-pastable example ```python import pandas as pd import numpy as np # Generate a 4x6 DataFrame df = pd.DataFrame(np.arange(24).reshape(4, 6), columns=list("abcdef")) # Make each column a different data type df = df.astype({"a":"float16", "b":"float32", "c":"float64", "d":"int8", "e":"int16", "f":"int32"}) print(df) # Output: # a b c d e f # 0 0.0 1.0 2.0 3 4 5 # 1 6.0 7.0 8.0 9 10 11 # 2 12.0 13.0 14.0 15 16 17 # 3 18.0 19.0 20.0 21 22 23 print(df.dtypes) # Output: # a float16 # b float32 # c float64 # d int8 # e int16 # f int32 # dtype: object # Rolling minimum across rows print(df.rolling(window=2, min_periods=1, axis=1).min()) # Output. Notice how the float16 and float32 columns were removed: # c d e f # 0 2.0 2.0 3.0 4.0 # 1 8.0 8.0 9.0 10.0 # 2 14.0 14.0 15.0 16.0 # 3 20.0 20.0 21.0 22.0 ``` #### Problem description It seems that rolling operations along rows (`axis=1`) incorrectly omit columns containing `float16`s and `float32`s. The same operations work as expected along columns (`axis=0`), however. #### Expected Output ```python # Convert float16 and float32 columns to float64s as a workaround df = df.astype({"a":"float64", "b":"float64"}) # Rolling minimum across rows again print(df.rolling(window=2, min_periods=1, axis=1).min()) # Output: # a b c d e f # 0 0.0 0.0 1.0 2.0 3.0 4.0 # 1 6.0 6.0 7.0 8.0 9.0 10.0 # 2 12.0 12.0 13.0 14.0 15.0 16.0 # 3 18.0 18.0 19.0 20.0 21.0 22.0 ``` #### Possible Cause A change made in #36458, [specifically this line](https://github.com/phofl/pandas/blob/fb85045056fc9cd773e714287a7a88ac55e19023/pandas/core/window/rolling.py#L250). It seems that `"float"` is an alias specifically for `np.float64`, not `np.float32` or `np.float16`. Changing that line to `obj = obj.select_dtypes(include="number", exclude=["timedelta"])` to include all numeric values seemed to fix the issue in this case. I can open a PR if there don't seem to be any issues with this. #### Output of ``pd.show_versions()`` <details> INSTALLED VERSIONS ------------------ commit : 2cb96529396d93b46abab7bbc73a208e708c642e python : 3.9.1.final.0 python-bits : 64 OS : Windows OS-release : 10 Version : 10.0.19041 machine : AMD64 processor : AMD64 Family 23 Model 8 Stepping 2, AuthenticAMD byteorder : little LC_ALL : None LANG : en_US.UTF-8 LOCALE : English_Canada.1252 pandas : 1.2.4 numpy : 1.20.3 pytz : 2021.1 dateutil : 2.8.1 pip : 21.1.2 setuptools : 57.0.0 Cython : None pytest : None hypothesis : None sphinx : None blosc : None feather : None xlsxwriter : None lxml.etree : 4.6.3 html5lib : None pymysql : None psycopg2 : None jinja2 : None IPython : 7.24.0 pandas_datareader: None bs4 : 4.9.3 bottleneck : None fsspec : None fastparquet : None gcsfs : None matplotlib : 3.4.2 numexpr : None odfpy : None openpyxl : 3.0.7 pandas_gbq : None pyarrow : None pyxlsb : None s3fs : None scipy : None sqlalchemy : None tables : None tabulate : None xarray : 0.18.2 xlrd : None xlwt : None numba : None </details>

- [X] I have searched the [[pandas] tag](https://stackoverflow.com/questions/tagged/pandas) on StackOverflow for similar questions. - [X] I have asked my usage related question on [StackOverflow](https://stackoverflow.com). --- What is the current state of amd64 compilation? Docker pip installation takes ages and I'm having trouble installing it on my macos with apple m1 chip. Is there anything I can do to help provide precompiled binaries for release on this platform?

- [x] I have checked that this issue has not already been reported. - [x] I have confirmed this bug exists on the latest version of pandas. - [ ] (optional) I have confirmed this bug exists on the master branch of pandas. --- **Note**: Please read [this guide](https://matthewrocklin.com/blog/work/2018/02/28/minimal-bug-reports) detailing how to provide the necessary information for us to reproduce your bug. #### Code Sample, a copy-pastable example ```python import pandas as pd pd.DataFrame({"i": [0, 1, 2], "b": [False, False, True], "s": ["x", "y", "z"]}).quantile(q=0.5, numeric_only=True) ``` #### Problem description https://github.com/numpy/numpy/pull/16273#discussion_r641264085 broke the case of NumPy's `percentile` with bools which causes to break pandas pandas' `quantile` too. If this is considered as not a bug, I would expect pandas to handle it with `numeric_only`. Cross filed issue in NumPy: https://github.com/numpy/numpy/issues/19154 Currently it throws an exception as below: ``` Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/.../python3.8/site-packages/pandas/core/frame.py", line 9266, in quantile result = data._mgr.quantile( File "/.../python3.8/site-packages/pandas/core/internals/managers.py", line 491, in quantile block = b.quantile(axis=axis, qs=qs, interpolation=interpolation) File "/.../python3.8/site-packages/pandas/core/internals/blocks.py", line 1592, in quantile result = nanpercentile( File "/.../python3.8/site-packages/pandas/core/nanops.py", line 1675, in nanpercentile return np.percentile(values, q, axis=axis, interpolation=interpolation) File "<__array_function__ internals>", line 5, in percentile File "/.../python3.8/site-packages/numpy/lib/function_base.py", line 3818, in percentile return _quantile_unchecked( File "/.../python3.8/site-packages/numpy/lib/function_base.py", line 3937, in _quantile_unchecked r, k = _ureduce(a, func=_quantile_ureduce_func, q=q, axis=axis, out=out, File "/.../python3.8/site-packages/numpy/lib/function_base.py", line 3515, in _ureduce r = func(a, **kwargs) File "/.../python3.8/site-packages/numpy/lib/function_base.py", line 4064, in _quantile_ureduce_func r = _lerp(x_below, x_above, weights_above, out=out) File "/.../python3.8/site-packages/numpy/lib/function_base.py", line 3961, in _lerp diff_b_a = subtract(b, a) TypeError: numpy boolean subtract, the `-` operator, is not supported, use the bitwise_xor, the `^` operator, or the logical_xor function instead. ``` #### Expected Output ``` i 1.0 b 0.0 Name: 0.5, dtype: float64 ``` #### Output of ``pd.show_versions()`` <details> ``` INSTALLED VERSIONS ------------------ commit : 2cb96529396d93b46abab7bbc73a208e708c642e python : 3.8.8.final.0 python-bits : 64 OS : Darwin OS-release : 20.4.0 Version : Darwin Kernel Version 20.4.0: Thu Apr 22 21:46:47 PDT 2021; root:xnu-7195.101.2~1/RELEASE_X86_64 machine : x86_64 processor : i386 byteorder : little LC_ALL : None LANG : en_US.UTF-8 LOCALE : en_US.UTF-8 pandas : 1.2.4 numpy : 1.20.3 pytz : 2021.1 dateutil : 2.8.1 pip : 21.0.1 setuptools : 52.0.0.post20210125 Cython : None pytest : 6.2.4 hypothesis : None sphinx : 3.0.4 blosc : None feather : None xlsxwriter : None lxml.etree : None html5lib : None pymysql : None psycopg2 : None jinja2 : 2.11.3 IPython : 7.23.1 pandas_datareader: None bs4 : 4.9.3 bottleneck : None fsspec : None fastparquet : None gcsfs : None matplotlib : 3.2.2 numexpr : None odfpy : None openpyxl : 3.0.7 pandas_gbq : None pyarrow : 4.0.0 pyxlsb : None s3fs : None scipy : 1.6.3 sqlalchemy : 1.4.14 tables : None tabulate : 0.8.9 xarray : None xlrd : 1.2.0 xlwt : None numba : None ``` </details>

- [x] I have checked that this issue has not already been reported. - [x] I have confirmed this bug exists on the latest version of pandas. - [ ] (optional) I have confirmed this bug exists on the master branch of pandas. --- #### Code Sample, a copy-pastable example ```python import numpy as np import pandas as pd print(pd.__version__) df = pd.DataFrame(["a", "b", np.nan]) print("astype(str): \n", df.astype(str)) print("astype('category').astype(str): \n", df.astype("category").astype(str)) ``` Output 1.1.3: ``` 1.1.3 astype(str): 0 0 a 1 b 2 nan astype('category').astype(str): 0 0 a 1 b 2 nan ``` Output 1.2.4: ``` 1.2.4 astype(str): 0 0 a 1 b 2 nan astype('category').astype(str): 0 0 a 1 b 2 NaN ``` #### Problem description The above snippet run on version 1.1 (tested on 1.1.3) returns `'nan'` strings of the converted categories, whereas on 1.2 (tested on 1.2.4) keeps `np.nan` objects. Tangentially, when using the pandas StringDtype conversion (`.astype("string")`, pandas 1.1 and 1.2 both keep a NAType after conversion from categorical to string. It is not clear whether it is expected behaviour that this conversion keeps `np.nan`, or whether it should return a `'nan'` string. The former would mean that this is now correct, the latter would mean there is a regression. This issue is probably related to https://github.com/pandas-dev/pandas/pull/37355 and https://github.com/pandas-dev/pandas/issues/25353 #### Expected Output Document what behaviour is desired. #### Output of ``pd.show_versions()`` <details> INSTALLED VERSIONS ------------------ commit : 2cb96529396d93b46abab7bbc73a208e708c642e python : 3.8.2.final.0 python-bits : 64 OS : Linux OS-release : 4.19.0-14-amd64 Version : #1 SMP Debian 4.19.171-2 (2021-01-30) machine : x86_64 processor : byteorder : little LC_ALL : None LANG : en_US.UTF-8 LOCALE : en_US.UTF-8 pandas : 1.2.4 numpy : 1.20.2 pytz : 2021.1 dateutil : 2.8.1 pip : 21.1.2 setuptools : 54.2.0 Cython : None pytest : None hypothesis : None sphinx : None blosc : None feather : None xlsxwriter : None lxml.etree : None html5lib : None pymysql : None psycopg2 : None jinja2 : 2.11.3 IPython : 7.22.0 pandas_datareader: None bs4 : 4.9.3 bottleneck : None fsspec : 0.8.7 fastparquet : None gcsfs : None matplotlib : 3.4.1 numexpr : None odfpy : None openpyxl : 3.0.7 pandas_gbq : None pyarrow : 4.0.0 pyxlsb : None s3fs : None scipy : 1.6.2 sqlalchemy : None tables : None tabulate : None xarray : None xlrd : 2.0.1 xlwt : None numba : 0.53.1 </details> Versions are identical except for one run at pandas 1.1.3, the other at 1.2.4.

Motivation: get rid of `_convert_listlike_indexer`, `_convert_arr_indexer`, `_convert_list_indexer`. These are just convoluted bits of casting before a (inefficient-because-repeated) call to `get_indexer`. This moves the relevant casting for the DTI/TDI/PI case directly into get_indexer, mirroring how get_loc works for these subclasses. Upcoming PR does analogous thing for IntervalIndex and CategoricalIndex. MultiIndex is the last one, haven't landed on a solution there. cc @phofl

In `pandas/_typing.py`, we define `ArrayLike` as: ```python ArrayLike = Union["ExtensionArray", np.ndarray] ``` In the numpy glossary https://numpy.org/doc/stable/glossary.html?highlight=array_like, numpy defines `array_like` as: > Any scalar or sequence that can be interpreted as an ndarray. In addition to ndarrays and scalars this category includes lists (possibly nested and with different element types) and tuples. Any argument accepted by numpy.array is array_like. Are we creating confusion by using the term `ArrayLike` to only mean arrays, whereas numpy defines it to include scalars? This came up in terms of reconciling the arguments of `np.searchsorted()` and `ExtensionArray.searchsorted()`. Comments from @jbrockmendel and @simonjayhawkins welcome.

Just about as much as we can simplify _try_cast until deprecations are enforced. Removes the last usage of construct_1d_ndarray_preserving_na, so removes that altogether

The axis along which interpolation is performed is different for different methods in interpolate. For example ``` df = pd.DataFrame(np.array([ [1, 2, 3], [5, np.nan, np.nan], [3, np.nan, 4], ])) print(df.interpolate(method='pad', axis='index')) print(df.interpolate(method='pad', axis='index', limit_area='inside')) ``` returns ``` 0 1 2 0 1.0 2.0 3.0 1 5.0 2.0 6.0 2 3.0 2.0 4.0 0 1 2 0 1.0 2.0 3.0 1 5.0 5.0 6.0 2 3.0 3.0 4.0 ``` Clearly with `limit_area` set the interpolation happens on the wrong axis. Not contributed before but happy to have a go at this one?

In `install.rst`, we list `setuptools` as a runtime dependency. If that is the case, we don't need to vendor `packaging` #41199 since it's vendored by `pkg_resources`, which is part of `setuptools`. And we need to update `setup.cfg` and `README.md` to reflect this. If `setuptools` is not a runtime dependency, vendoring `packaging` is necessary. And, we need to list it as a test and optional dependency because we are using `pkg_resources` in `pandas/plotting/_core.py` and `pandas/tests/plotting/test_backend.py` #41503. An alternative of `pkg_resources` for accessing entry points is `importlib.metadata`, which is only available after Python 3.8. And `importlib.metadata` is the suggested way to do this according to https://setuptools.readthedocs.io/en/latest/pkg_resources.html.

- [X] I have checked that this issue has not already been reported. - [X] I have confirmed this bug exists on the latest version of pandas. - [X] (optional) I have confirmed this bug exists on the master branch of pandas. --- #### Code Sample, a copy-pastable example ```python pd.util.hash_array(pd.DatetimeIndex(['2018-10-28 01:20:00'], tz='Europe/Berlin')) ``` Output: ``` --------------------------------------------------------------------------- AttributeError Traceback (most recent call last) <ipython-input-2-389898c5af02> in <module> ----> 1 pd.util.hash_array(pd.DatetimeIndex(['2018-10-28 01:20:00'], tz='Europe/Berlin')) ~/.pyenv/versions/3.8.6/envs/beam/lib/python3.8/site-packages/pandas/core/util/hashing.py in hash_array(vals, encoding, hash_key, categorize) 255 return _hash_categorical(vals, encoding, hash_key) 256 elif is_extension_array_dtype(dtype): --> 257 vals, _ = vals._values_for_factorize() 258 dtype = vals.dtype 259 AttributeError: 'DatetimeIndex' object has no attribute '_values_for_factorize' ``` Apparently `datetime64[ns, Europe/Berlin]` is an extension array dtype but has no `_values_for_factorize` method. I've reproduced on pandas 1.1.4, 1.2.4, and on master (503ce5045d8344b69207ae045943644bd0a14881) #### Problem description `pd.util.hash_array` works with other Indexes, including a timezone-naive `DatetimeIndex`, it seems reasonable to expect it to work with a timezone-aware `DatetimeIndex` (or yield a better error). #### Expected Output Output should be similar to timezone-naive `DatetimeIndex`: ```python In [3]: pd.util.hash_array(pd.DatetimeIndex(['2018-10-28 01:20:00'])) Out[3]: array([3152239034440746192], dtype=uint64) ```

- [x] I have checked that this issue has not already been reported. - [x] I have confirmed this bug exists on the latest version of pandas. - [] (optional) I have confirmed this bug exists on the master branch of pandas. --- **Note**: Please read [this guide](https://matthewrocklin.com/blog/work/2018/02/28/minimal-bug-reports) detailing how to provide the necessary information for us to reproduce your bug. #### Code Sample, a copy-pastable example This is a line in a file named as `data.txt` and I am trying to read this in pandas using `read_csv`. `"xxx"|"xxx"|"-xxxxxxx"|"xxxxx"|"x"|"xx"|""xxxxxx""|"x"|"xx"|"xxxxxxx"|""|"x"|"xxxxxx"|"X"|"xxxx"|"xxxxx"|""` ``` df = pd.read_csv('data.txt', names=columns, dtype=column_dict, na_values=[''], keep_default_na=False, sep='|', encoding='cp1252', skiprows=1) ``` #### Problem description The problem I am facing here is that even though all the other data are read in the data frame correctly, pandas has an issue when it comes to reading ""xxxxxx"" two double quotes and it reads it as xxxxxx"" inside the dataframe As you can notice there is in the 7th index in the above line, there is an item with double-double quotes, that is the issue #### Expected Output The expected output should be that it should be read as "xxxxxx" inside the data frame #### Output of ``pd.show_versions()`` INSTALLED VERSIONS ------------------ commit : 2cb96529396d93b46abab7bbc73a208e708c642e python : 3.8.5.final.0 python-bits : 64 OS : Linux OS-release : 5.4.0-1043-gcp Version : #46-Ubuntu SMP Mon Apr 19 19:17:04 UTC 2021 machine : x86_64 processor : x86_64 byteorder : little LC_ALL : None LANG : C.UTF-8 LOCALE : en_US.UTF-8 pandas : 1.2.4 numpy : 1.20.3 pytz : 2021.1 dateutil : 2.8.1 pip : 20.0.2 setuptools : 44.0.0
