Fixes CI for Windows 3.7 np1.6; regression in scipy 1.6.1 (https://github.com/scipy/scipy/issues/13585)
Alternative would be to pin build, wasn't sure which is prefered over the other. Will open tracking issue once the method is decided. | {

https://github.com/pandas-dev/pandas/blob/dec7d213fb27e9eafb61201f173c241d7105f772/pandas/tests/extension/test_numpy.py#L36-L54
However, this regularly gives problems, see eg https://github.com/pandas-dev/pandas/pull/39991#discussion_r581114674 or https://github.com/pandas-dev/pandas/pull/39722#discussion_r573896611, where for some reason those PandasArrays do / don't get preserved in a DataFrame/Series due to some other code changes that impact this, and the tests are not written to deal with it.
(one example: `extract_array` will convert a pandas Series with numpy dtype into a PandasArray, when the patch is enabled. This can then cause the result to include the PandasArray EA, while the expected result is not created that way)
So we should try to find a solution for this (as it gets quite annoying to deal with it just to get those tests passing). But I don't directly know what the best solution would be.
Some ideas:
- Simply remove `tests/extension/test_numpy.py` and thus don't run the base extension interface tests for PandasArray. We still have `tests/arrays/test_numpy.py` for some other tests. The easiest solution, but would also remove test coverage.
- In some way only run the tests in `tests/extension/test_numpy.py` that only deal with the array, and not with the array stored in DataFrame/Series.

xerf #37277 cc @TomAugspurger this is failing one of the dask tests locally, looks like dask is calling `index.array`. Thoughts on how to handle this?
Might be worth folding the RangeIndex check into a keyword in extract_array. | {

I recently posted an inquiry on Stack Overflow requesting assistance regarding Pandas and down-sampling. I had some forward binned data, particle counts logged at various diameters:
296.54,303.14,311.88,320.87,330.12,339.63,349.42,359.49,369.86,380.52,391.49,402.77 nm
The counts were logged at between 296.54 and 303.14 nm, and so on.
I wanted to re-bin those counts to a new set of diameters:
300,325,350,375,400 nm
where the counts would be logged between 300 and 325 nm and so on.
I had to, column by column, brute force add and interpolate matching diameters. For instance the 300-325 nm bin would contain part of the 296-303 bin, plus the bins up to 320 nm, and part of the 320-330nm bin. and so on.
#### Describe the solution you'd like
I would like to see a solution where one pandas dataframe can be interpolated to not a higher resolution, but a lower one, set by a second set of values, either on columns (my specific example) or indices. Currently the interpolate function only fills missing data, it does not, to my knowledge, completely rebuild the dataframe to an entirely new resolution, one that may not, in fact, be uniformly distributed.
#### API breaking implications
[this should provide a description of how this feature will affect the API]
#### Describe alternatives you've considered
The challenge is that the size spectrum cannot be linearly interpreted between the smallest and largest diameters. So a simple sum, re-index and interpolate would not conserve spectral data.
Nor does the resample function do the trick since it applies to datetime indices only.
#### Additional context
This particular example if for forward-binned data. Some thought would have to be given to manage backward-binned or center-binned data.
### My code example
I apologize for the crudity, but I am not a Pandas developer. Here is what my implementation ended up being:
```python
# set up a 10x12 test array
test_array=(np.arange(120)).reshape(10,12)
# set a simple index
index_list=list(string.ascii_lowercase)[:10]
# initialize the high-resolution dataframe
df=pd.DataFrame(test_array, index=index_list)
# set the high-resolution column headers
df.columns=[296.54,303.14,311.88,320.87,330.12,339.63,349.42,359.49,369.86,380.52,391.49,402.77]
# set a column diameter array to search sort through
df_column_array=np.array(df.columns)
# set the new low-resolution diameters
new_columns=np.array([300,325,350,375,400])
# intialize a low-res dataframe
new_df=pd.DataFrame(columns=new_columns,index=index_list)
# loop through the low-res columns up to the second last (since these bins are forward counted)
for i,column in enumerate(new_columns[:-1]):
df_columns_backward_index=np.searchsorted(df.columns,column)-1 # locate the closest high-res bin before the current low res bin
df_columns_forward_index=np.searchsorted(df.columns,new_columns[i+1]) # locate the closest high-res bin after the current low res bin
backward_bin_size=df.columns[df_columns_backward_index+1]-df.columns[df_columns_backward_index] # calculate the first high-res bin size
# calculate the offset and fraction for interpolation
backward_offset=column-df.columns[df_columns_backward_index]
backward_fraction=1-backward_offset/backward_bin_size
# repeat for the last high-res bins closest to the current low-res bin
forward_bin_size=df.columns[df_columns_forward_index]-df.columns[df_columns_forward_index-1]
forward_offset=df.columns[df_columns_forward_index]-new_columns[i+1]
forward_fraction=1-forward_offset/forward_bin_size
# sum the fraction of high-res bins partially in the low-res bin along with the high-res bins fully within the low-res bin
new_df[column]=df.iloc[:,df_columns_backward_index]*backward_fraction+df.iloc[:,df_columns_backward_index+1:df_columns_forward_index-1].sum(axis=1)+df.iloc[:,df_columns_forward_index-1]*forward_fraction

#### Code Sample, a copy-pastable example
```python
import pandas as pd
df = pd.DataFrame(data={'x': [1000.0, 'test']}) # Column dtype must be object
df.to_html(float_format=lambda x: '{:,.0f}'.format(x))
```
#### Output:
```html
'<table border="1" class="dataframe">\n <thead>\n <tr style="text-align: right;">\n <th></th>\n <th>x</th>\n </tr>\n </thead>\n <tbody>\n <tr>\n <th>0</th>\n <td>1,</td>\n </tr>\n <tr>\n <th>1</th>\n <td>test</td>\n </tr>\n </tbody>\n</table>'
```
#### Problem description
This caused by the rstrip in pandas.io.formats.format._trim_zeros_single_float()
#### Expected Output
```html
'<table border="1" class="dataframe">\n <thead>\n <tr style="text-align: right;">\n <th></th>\n <th>x</th>\n </tr>\n </thead>\n <tbody>\n <tr>\n <th>0</th>\n <td>1,000</td>\n </tr>\n <tr>\n <th>1</th>\n <td>test</td>\n </tr>\n </tbody>\n</table>'
```

The main remaining blocker to that is downstream usage. @jorisvandenbossche i know pyarrow accesses some of core.internals, do you know if it is just `make_block` or is anything else accessed? | {

It seems the two do not play well together:
```
df = pd.DataFrame([[1,2],[3,4]])
df.iloc[0,0] = np.nan
df.style.set_na_rep('MISS').set_precision(1)
MISS | 2
3.0 | 4
df.style.set_na_rep('MISS').format('{:,.1f}')
nan | 2.0
3.0 | 4.0
df.style.set_na_rep('MISS').format('{:,.1f}', na_rep='PASS')
PASS | 2.0
3.0 | 4.0
```
could probably do with a review how the attribute `na_rep` interacts with the formatter and try to make it more dynamic or use pointers instead of static value, if possible. | {

Proposed speed up for very simple use cases using the `pd.json_normalize` function. E.g. `pd.json_normalize(data)`
The speed up can be seen in this example:
```
import datetime
import pandas as pd
# example json data
data = {"hello": ["thisisatest", 999898, datetime.date.today()],
"nest1": {"nest2": {"nest3": "nest3_value", "nest3_int": 3445}},
"nest1_list": {"nest2": ["blah", 32423, 546456.876, 92030234]},
"hello2": "string"}
hundred_thousand_rows = [data for i in range(100000)]
s = time()
pd.json_normalize(hundred_thousand_rows)
pandas_json_normalize_time_taken = time() - s
print(f"\npandas time taken for a 100,000 rows: {pandas_json_normalize_time_taken} seconds")
```
With output from Pandas 1.2.2: `pandas time taken for a 100,000 rows: 3.0518009662628174 seconds`
From this branch: `pandas time taken for a 100,000 rows: 0.632451057434082 seconds`
To show tests pass for the appropriate file, ran `pytest pandas/tests/io/json/test_normalize.py -v` [test_normalize.py_pytest.log](https://github.com/pandas-dev/pandas/files/6039361/test_normalize.py_pytest.log)
To show pre-commit passed on file, ran `pre-commit run --files pandas/io/json/_normalize.py` [_normalize.py_pre-commit.log](https://github.com/pandas-dev/pandas/files/6039363/_normalize.py_pre-commit.log)
There was one code check that was caught, running `./ci/code_checks.sh` [code_checks.log](https://github.com/pandas-dev/pandas/files/6039360/code_checks.log)
```
pandas/io/json/_normalize.py:208: error: Incompatible types in assignment (expression has type "List[Union[List[Dict[Any, Any]], Dict[Any, Any]]]", variable has type "Dict[Any, Any]") [assignment]
```
As it a type hint issue, decided to still make pull request. Can you advice on how to fix, I'm fairly new to type hints?
Kind regards,

Currently, for large CSV files, pandas parse a column with mixed data types with only a warning (DtypeWarning)
[https://github.com/pandas-dev/pandas/blob/v1.2.2/pandas/errors/__init__.py#L57-L112](url)
[https://github.com/pandas-dev/pandas/blob/master/pandas/_libs/parsers.pyx](url)
This behavior of keeping mix data type in a column is totally unexpected and a warning for it is not enough.
#### Describe the solution you'd like
Just convert all the values of the column to one type and produce a warning. For example, if it is a mix of int and object, just convert all to object and then produce a warning. This way, there would be no unexpected behavior/error later in the manipulation of DataFrame.
#### API breaking implications
API will not change. The behavior of API becomes more predictable.

#### Code Sample, a copy-pastable example
```python
import pandas as pd
import numpy as np
ROWS=[1000, 2000, 4000, 8000, 16000, 32000]
for rows in ROWS:
print("rows", rows)
df = pd.DataFrame({"a": np.random.randint(0, rows, size=rows).astype(str), "b": range(0, rows)})
%timeit df.groupby("a").apply(lambda x: x.head(1))
for rows in ROWS:
print("rows", rows)
df = pd.DataFrame({"a": np.random.randint(0, rows, size=rows).astype(str), "b": range(0, rows)})
%timeit df.groupby("a").apply(lambda x: x.max())
```
#### Problem description
As a result of comparing 1.2.2 with 0.25.3, 1.2.2 is much slower. In particular, the head processing time is proportional to the number of lines in 0.25.3, but in 1.2.2, when the number of lines doubles, the processing time triples.

#### Code Sample, a copy-pastable example
```python
import pandas as pd
from datetime import datetime, timedelta
s1 = pd.Series([138, 2377900603251717750], index=pd.Index([datetime(year=1970, month=1, day=1), datetime(year=1970, month=1, day=1)+timedelta(microseconds=1)]))
s2 = s1.rolling("1D").sum()
print(s2.sum() >= s1.sum())
```
#### Problem description
The sum of the rolling window should be higher or equal to the original series because only positive values are in it. However, 'False' is printed.
#### Expected Output
True
#### Output of ``pd.show_versions()``

#### Code Sample, a copy-pastable example
```python
import pandas as pd
class TestClass:
def __init__(self, num):
self.num = num
self._values = []
def __add__(self, other):
return TestClass(self.num + other.num)
s = pd.Series(
[TestClass(1), TestClass(2), TestClass(3)],
index=pd.Index([0,1,1], name="ind"),
)
s.sum()
s.groupby("ind").sum()
```
#### Problem description
s.sum() works but, for pandas >= 1.2.0, s.groupby("ind").sum() results in the following error:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Users\rclement\tempenv\lib\site-packages\pandas\core\groupby\groupby.py", line 1654, in sum

result, counts = grouper.get_result()
File "pandas\_libs\reduction.pyx", line 260, in pandas._libs.reduction.SeriesGrouper.get_result
File "pandas\_libs\reduction.pyx", line 77, in pandas._libs.reduction._BaseGrouper._apply_to_group
File "pandas\_libs\reduction.pyx", line 289, in pandas._libs.reduction.extract_result
AttributeError: 'list' object has no attribute 'ndim'
The error is due to an assumption in pandas\_libs\reduction.pyx in the following function, where if the result of the sum has an attribute _values, then it is also assumed to have an attribute ndim (and the __len__ method), which is not necessarily true for user defined objects like "TestClass"
```python
cpdef inline extract_result(object res, bint squeeze=True):
""" extract the result object, it might be a 0-dim ndarray
or a len-1 0-dim, or a scalar """
if hasattr(res, "_values"):
# Preserve EA
res = res._values
if squeeze and res.ndim == 1 and len(res) == 1:
res = res[0]
if hasattr(res, 'values') and is_array(res.values):
res = res.values
if is_array(res):
if res.ndim == 0:
res = res.item()
elif squeeze and res.ndim == 1 and len(res) == 1:
res = res[0]
return res
```
#### Expected Output
```python
>>> s.sum()
<__main__.TestClass object at 0x000002359C7F2C08>
>>> s.groupby("ind").sum()
ind
0 <__main__.TestClass object at 0x000002359C7F2E48>
1 <__main__.TestClass object at 0x000002359C80B788>
dtype: object
```
We could check hasattr(res, "ndim") and hasattr(res, "__len__") is True, before trying to access those attributes, but it seems like the check for _values attribute is being used as a proxy for a more concrete assumption, eg is the result a pandas object? Could the check for _values attribute be replaced with a more explicit check?

So, in #27808 , `leg.legendHandles` was replaced with `ax.get_legend_handles_labels()[0]` in order to preserve marker info.
However, `ax.get_legend_handles_labels()[0]` may contain extra elements which aren't (yet) visible, which means we may end up at
https://github.com/pandas-dev/pandas/blob/272435073c70b4421f72184663837f4864601f11/pandas/plotting/_matplotlib/core.py#L625
with
```python
(Pdb) handles
[<matplotlib.lines.Line2D object at 0x7f0938a37430>, <ErrorbarContainer object of 3 artists>, <matplotlib.lines.Line2D object at 0x7f0938a37430>]
(Pdb) labels
['orange', 'blue']
```
This causes the permuting noted in #39522
Ideally, there would be a way to get `leg.legendHandles` in a way that preserves the marker info. However, I can't find a way to do that - have asked on the matplotlib discourse. Also, the current test doesn't quite work (as it passes on `master` too). I'm working on finding a satisfactory solution

#### Code Sample, a copy-pastable example
Bad CSV file:
```csv
A,B,C
foo,1,2
bar,bar,3,4
baz,5,6
```
Python code:
```python
import pandas as pd
df_all = pd.read_csv('bad.csv', error_bad_lines = False, warn_bad_lines = False)
print(df_all)
# A B C
# 0 foo 1 2
# 1 baz 5 6
df_sub = pd.read_csv('bad.csv', error_bad_lines = False, warn_bad_lines = False, usecols = ['A','B'])
print(df_sub)
# A B
# 0 foo 1
# 1 bar bar
# 2 baz 5
```
#### Problem description
As can be seen in the example above, when not using `usecols`, `read_csv` correctly ignores the line that is too long.
However, this is not the case when `usecols` is used.
#### Expected Output
Using `usecols` should not affect which lines are discarded due to being too long.
#### Output of ``pd.show_versions()``

This passes / skips all groupby tests (in `/tests/groupby`). Actual code changes:
- fix `groupby().count()` to not create a ArrayManager with 2D arrays
- for now skip the usage of `fast_apply` / `libreduction.apply_frame_axis0` for DataFrames with ArrayManager. This can be tackled separately, while for now already getting more test coverage by using the python fallback (as we eg also do for EAs).
- implement `ignore_failures` for `ArrayManager.grouped_reduction` (this keyword is actually always True at the moment, so we could also leave away the keyword itself)
Most of the skips are related `quantile` (or `describe`) not yet being implemented. And it also uncovered a few other failures, that can be worked on as follow-ups.

Idea: put the ndarray-wrapping methods in cython
Upsides: performance! stats currently pasted into the NDArrayBacked docstring:
```
import pandas as pd
from pandas._libs.lib import NDArrayBacked as cls
dti = pd.date_range("2016-01-01", periods=3)
dta = dti._data
arr = dta._ndarray
obj = cls._simpler_new(arr, arr.dtype)
# for foo in [arr, dta, obj]: ...
%timeit foo.copy()
299 ns ± 30 ns per loop # <-- arr underlying ndarray (for reference)
530 ns ± 9.24 ns per loop # <-- dta with cython NDArrayBacked
1.66 µs ± 46.3 ns per loop # <-- dta without cython NDArrayBacked <-- i.e. master
328 ns ± 5.29 ns per loop # <-- obj with NDArrayBacked.__cinit__
371 ns ± 6.97 ns per loop # <-- obj with NDArrayBacked._simpler_new
%timeit foo.T
125 ns ± 6.27 ns per loop # <-- arr underlying ndarray (for reference)
226 ns ± 7.66 ns per loop # <-- dta with cython NDArrayBacked
911 ns ± 16.6 ns per loop # <-- dta without cython NDArrayBacked <-- i.e. master
215 ns ± 4.54 ns per loop # <-- obj with NDArrayBacked._simpler_new
```
i.e. `dta.copy()` is 3x faster, and within 2x of numpy. With further tweaks we could get within 10% of numpy (the 328 ns number). `dta.T` is 4x faster and within 2x of numpy.
(T is more-improved than copy bc we override copy in python to copy `.freq`)
Downsides: 1) pickle is a PITA, 2) constructor gymnastics
Future:
- lib.pyx is likely not the best place for this
- can squeeze out more perf if we use `__cinit__`; requires more constructor gymnatics
- can use in PeriodArray, Categorical, PandasArray with some effort
- more methods could be optimized

The columns in a DataFrame have names. When you iterate over a groupby object and get the names of the groups (which correspond to values in the original DataFrame), the group names are returned as ordinary `tuple`s and so their correspondence to the columns of the DataFrame is lost. Fields in the `name` tuple can only be accessed by their index; the more natural option of using the corresponding column name in the original DataFrame is not possible.
#### Describe the solution you'd like
When iterating over a groupby -- `for name, group in df.groupby(...):` -- `name` should be a `namedtuple` instead of an ordinary `tuple` so as to allow accessing fields by column name. Any other function that returns the name of a group should return it as a `namedtuple` and not a tuple. The ordinary considerations about what happens when an invalid Python identifier is used as a `namedtuple` field should occur (I think they get replaced with `_1`, `_2`, etc, but not sure about this), especially when the columns have names that are not strings.
#### API breaking implications
As far as I know, `namedtuple`s expose a strict superset of the API of `tuple`s, so there shouldn't be any breaking changes.
#### Describe alternatives you've considered
This very ugly solution:
grouping_cols = ["col1", "col2"]
g = df.groupby(grouping_cols)
name, _ = next(iter(g))
name_col1 = name[grouping_cols.index("col1")]
# now name_col1 is the value in the `name` tuple corresponding to the `"col1"` column
#### Additional context
Ideally I could simply write `name.col1`. | {

- [ ] whatsnew entry
The issue is that there are currently two competing methods in `Styler` for missing value represenatation:
- `.set_na_rep('x')` and
- `.format(na_rep='y')`.
The two do not interact well together dynamically. This PR brings the `format wrapping` into the class so that `format` can be updated and inherit values in `set_na_rep` after it has been called. The image below highlights the impact this PR has and the added test replicates this pattern:
Also at the bottom here, we add a `KeyError` to remove the ambiguity between what happens when a dict is provided with a column Key that is not specifically included within the provided `subset` slice.

Hunting this down, I'm replicating the most-weird benchmark (asv reports 1.27±0ms vs 789±3μs) in ipython
```
arr = np.ones(10**6, dtype="int8")
ser = pd.Series(arr)
func = ser.sum
%timeit func()
```
The first few runs matched the asv results really closely:
```
In [4]: %timeit func()
781 µs ± 552 ns per loop (mean ± std. dev. of 7 runs, 1000 loops each) # <-- branch
1.27 ms ± 1.82 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each) # <-- master
```
But running it again just for kicks the results flipped:
```
In [5]: %timeit func()
1.27 ms ± 5.05 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each) # <-- branch
780 µs ± 4.81 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each) # <-- master
In [5]: %timeit func()
1.26 ms ± 691 ns per loop (mean ± std. dev. of 7 runs, 1000 loops each) # <-- branch
1.26 ms ± 578 ns per loop (mean ± std. dev. of 7 runs, 1000 loops each) # <-- master
In [10]: %timeit func()
1.26 ms ± 818 ns per loop (mean ± std. dev. of 7 runs, 1000 loops each) # <-- branch
773 µs ± 200 ns per loop (mean ± std. dev. of 7 runs, 1000 loops each) # <-- master
```
Eventually the ~780 number stopped showing up and got replaced a mode between 895-907, but the 1.26-1.27 mode hasn't moved a bit.
No obvious pattern as to which mode will show up in any given run (through they are positively auto-correlated). But in the asv results there must be something causing the modes to be split between the two branches.
I get the same behavior even if I use the same branch, just different terminal windows.
Looking at this with `%prun -s cumtime for i in range(1000): func()` points at `{method 'reduce' of 'numpy.ufunc' objects}`

The total difference is 1.292 - 0.796 = 0.496 and the difference in the `reduce` ufunc is 1.234 - 0.737 = 0.497, which is pretty suggestive. | {

**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
# prepare a dataframe where problem becomes obvious (details not important)
df = pd.DataFrame({'A': [1] * 20 + [2] * 12 + [3] * 8,
'B': np.arange(40)})
df = df.reset_index().set_index(['index','A']).reorder_levels([1,0])
index_mapping = {a:(a-20)/10 for a in range(20,32)}
df = df.rename(index=index_mapping)
index_mapping = {a:(a-32)/10 for a in range(32,40)}
df = df.rename(index=index_mapping)
df = df.rename_axis(index={'index':'time'})
# groupby - rolling operation (here is the bug)
df.groupby('A').rolling(4).mean()
```
#### Problem description
Applying groupby.rolling on a multiindex dataframe should preserve the level that the rolling operation is applied to. Instead that index level is removed. This loses information and causes non-unique index values.
### **df**
<img width="97" alt="Screen Shot 2021-02-25 at 4 58 03 PM" src="https://user-images.githubusercontent.com/35338267/109225102-d2c12e80-778a-11eb-92b5-27e094b60c78.png">
### **df after applying groupby('A').rolling misses index level 'time'**
<img width="73" alt="Screen Shot 2021-02-25 at 4 58 09 PM" src="https://user-images.githubusercontent.com/35338267/109225082-cb9a2080-778a-11eb-9ee8-c76351852e71.png">
#### Expected Output
All index levels should be preserved. In older versions of pandas (1.1.2) the index levels were preserved, but there used to be a different bug: The whole multilevel index structure was duplicated, leading to twice the number of original levels. I guess that in an attempt to fix this, this new bug got introduced.

#### Code Sample, a copy-pastable example
```python
d1 = pd.DataFrame([("a",)], columns=["id"], dtype="string")
d2 = pd.DataFrame([("b",)], columns=["id"], dtype="string")
result = d1.merge(d2, on="id", how="outer")
dtype = result.dtypes["id"]
print(dtype) # expected 'string', but is 'object'
```
#### Problem description
When doing an outer merge on a column of type `string`, the result contains this column with the type `object`. This makes it more difficult to use the new `string` type.
The problem doesn't occur with the types `Int32`, `Float32`, `boolean`. It seems to be specific to the `string` type.
The problem doesn't occur with a left, right or inner-merge.

Currently the 0/1 -> 1/0 axis switch for the BlockManager happens on the DataFrame side, while I think it would be a bit cleaner to let this be the responsibility of the BlockManager method being called.
For illustration, the diff of this PR is such a change for the `diff()` method: instead of using `_get_block_manager_axis` in frame.py, it's the `BlockManager.diff()` method that takes care of this (so just moving it down a level). | {

raise AssertionError(msg)
AssertionError: DataFrame.index are different
DataFrame.index classes are not equivalent
[left]: Index([], dtype='object')
[right]: RangeIndex(start=0, stop=0, step=1)
```
#### Problem description
When creating an empty dataframe it is created with `Index`, and not with a `RangeIndex` as specified in the [docs](https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.html). This is a problem, e.g. in the example shown above, where I would not expect the index to change when appending the empty dataframe to itself. However, `pd.testing.assert_frame_equals` raises `AssertionError` since the indeces are not equivalent.
#### Expected Output
```python
>>> df = pd.DataFrame(columns=['a', 'b'])
>>> print(df.index)
RangeIndex(start=0, stop=0, step=1)
```
#### Output of ``pd.show_versions()``

This PR factors out adding ` (right)` to labels which are meant to go on the right y-axis. This does not change anything user-facing, and is simply a precursor to fixing #40044 and #39522 .
The change is that on `master`, only `leg.get_texts()` shows `b (right)` while `ax.right_ax.get_legend_handles_labels()` shows `b`. The former is used for constructing the user-facing legend. The reason I think it needs doing is that I believe that to address #40044 and #39522, we need to use `.get_legend_handles_labels()` for both handles and labels, while currently `.get_legend_handles_labels` is used for handles and `leg.get_texts()` is used for labels.

```python
(Pdb) ax.right_ax.get_legend_handles_labels()

Coming from [here](https://github.com/pandas-dev/pandas/issues/13432#issuecomment-786604695), I tried my issue on current HEAD@master and the erroneous behaviour still persists.
#### Code Sample, a copy-pastable example
```python
import pandas as pd
cat = pd.CategoricalDtype(categories=[1, 2, 3, 4])
df = pd.DataFrame({'a': [1, 2, 3, 4, 3, 2, 1], 'b': [4, 3, 2, 3, 1, 2, 3]}, dtype=cat)
# flat categorical index, no MultiIndex
df_cat = df.set_index('a', drop=False)
diff_ind = df_cat.index.difference(df_cat.head(3).index)
print(diff_ind.dtype) # -> category
union_ind = df_cat.index.union(df_cat.head(3).index)
print(union_ind.dtype) # -> category
# same set operations on MultiIndex, categorical gets lost
df_cat_multi = df.set_index(['a', 'b'], drop=False)
# just make sure, we have a categorical in the first place
print(df_cat_multi.index.get_level_values(0).dtype) # -> category
print(df_cat_multi.index.get_level_values(1).dtype) # -> category
diff_multi_ind = df_cat_multi.index.difference(df_cat_multi.head(3).index)
print(diff_multi_ind.get_level_values(0).dtype) # -> int64
print(diff_multi_ind.get_level_values(1).dtype) # -> int64
union_multi_ind = df_cat_multi.index.union(df_cat_multi.head(3).index)
print(union_multi_ind.get_level_values(0).dtype) # -> int64
print(union_multi_ind.get_level_values(1).dtype) # -> int64
```
#### Problem description
In contrast to set operations involving flat categorical indices, the same operations on multi-indices with categorical level values revert the result back to the underlying datatype.
#### Expected Output
The set-operations on multi-indices should preserve the categorical dtype of level values.
#### Output of ``pd.show_versions()``

#### Question about pandas
Hello,
I'm the maintainer of a Python library to store and manipulate (disjunctions of) intervals of arbitrary values (as long as they are comparable). It's called `portion` and it's available on PyPI and also on GitHub (https://github.com/AlexandreDecan/portion).
This data type defines a `__repr__` method (e.g. the interval from 0 to 1 included is represented as "[0,1]"). When I use this data type in `pandas`, I got a representation that does not correct to what can be expected. Let me provide a very simple example:
```python
>>> import portion as P
>>> P.closed(0, 1)
[0,1]
>>> import pandas as pd
>>> df = pd.DataFrame([P.closed(0,1)])
>>> df
| 0
-- | --
((([0,1])))
```
As you can see, the expected output has three extra "(" and three extra ")", this is:
EXPECTED OUTPUT= "[0,1]"
CURRENT_OUTPUT = "((([0,1])))"
The same occurs when I display the corresponding index:
```python
>>> df.loc[0]
0 ((([0,1])))
Name: 0, dtype: object
```
But not when I display the corresponding "cell":
```python
>>> df.loc[0][0]
[0,1]
```
Actually, if I get the object from `df.loc[0][0]`, I got the correct instance and its expected behaviour.
I looked at how `__repr__` is handled by `pandas` but couldn't find the reason why this occurs.
For what is worth, here's the implementation of `__repr__` in `portion`(see https://github.com/AlexandreDecan/portion/blob/master/portion/interval.py#L584):
```python
def __repr__(self):
intervals = []
for interval in self:
if interval.empty:
intervals.append('()')
elif interval.lower == interval.upper:
intervals.append('[{}]'.format(repr(interval.lower)))
else:
intervals.append(
'{}{},{}{}'.format(
'[' if interval.left == Bound.CLOSED else '(',
repr(interval.lower),
repr(interval.upper),
']' if interval.right == Bound.CLOSED else ')',
)
)
return ' | '.join(intervals)
```
In the above snippet, `self` is an `Interval` instance that can be iterated over. Each `interval in self` is an `Interval` instance as well (they correspond to all the atomic intervals you can have in a disjunctive one, e.g., "[0,1] | [3,4]" has two atomic intervals: [0,1] and [3,4]). Each `interval` has several attributes, but the ones of interest here are `left` and `right` (either `Bound.CLOSED` or `Bound.OPEN`, two constants from an enum based on Booleans), and `upper` and `lower` that respectively correspond to the upper bound of the interval and the lower bound of the interval (e.g., for [0,1], upper = 1, and lower = 0).
FYI, I'm using pandas 1.2.2 but I already got this "issue" with a previous version (unfortunately, I do not remember which one).
Thank you!

Currently on master, `agg` does some preprocessing on dict-like arguments that `transform` does not, leading to incorrect behavior in `transform`. This PR moves `agg`'s preprocessing into `validate_dictlike_arg` which is used by both `agg` and `transform`, fixing the issue.
As identified [in #40018](https://github.com/pandas-dev/pandas/issues/40018#issuecomment-785678614), this is a regression from 1.1 -> 1.2 (almost certainly from one of my PRs, but I haven't checked which). Backporting this to 1.2 will probably require a bit of a different fix. | {

---
The unit test at `pandas/tests/io/test_common.py` produces a file using a hardcoded name as shown below:
```python
filename = path_type("~/sometest")
with icom.get_handle(filename, "w") as handles:
assert os.path.isabs(handles.handle.name)
assert os.path.expanduser(filename) == handles.handle.name
```
#### Problem description
A developer may encounter an empty file "sometest" appearing in their home directory (after running `pytest`). If the developer is unaware of that, then it may raise some wrong security concerns on their side. Also, in the extreme scenario that the developer has a file at the exact same path, then its content may be replaced.
#### Expected Output
I would expect the file produced by the unit test to be temporary and get deleted afterwards. Also, that the filename is generated rather than hardcoded. | {

Moves relevant tests into test_invalid_arg. Had to rename two tests because they were of the same name, but no other changes. I organized the file by the reason for the exception, and indicated this at the top of the file. Certainly open to any other ways of organizing. | {

- [X] I have confirmed this bug exists on the latest version of pandas.
#### Code Sample
```python
import pandas as pd
d = pd.DataFrame(dict(a = range(10)))
def f(x):
print(x)
if x.iloc[0,0] == 2:
raise Exception('problem')
print(d.groupby('a').apply(f))
```
The result is
```
a
0 0
a
1 1
a
2 2
a
0 0
a
1 1
a
2 2
Traceback (most recent call last):
File "/tmp/ex.py", line 10, in <module>
print(d.groupby('a').apply(f))
File "/usr/local/lib/python3.8/dist-packages/pandas/core/groupby/groupby.py", line 894, in apply
result = self._python_apply_general(f, self._selected_obj)
File "/usr/local/lib/python3.8/dist-packages/pandas/core/groupby/groupby.py", line 928, in _python_apply_general
keys, values, mutated = self.grouper.apply(f, data, self.axis)
File "/usr/local/lib/python3.8/dist-packages/pandas/core/groupby/ops.py", line 238, in apply
res = f(group)
File "/tmp/ex.py", line 8, in f
raise Exception('problem')
Exception: problem
```
#### Problem description
If the `func` given to `GroupBy.apply(func)` raises an exception, the exception is suppressed and the application loop restarts from the beginning. My guess is that this is related to the behavior of one of pandas's `apply` functions that's supposed to ignore exceptions only for the first iteration, or only when an empty argument is provided, to guess the appropriate shape for the output.
#17326 may be related.
#### Expected Output
The loop shouldn't catch the exception, terminating as soon as it hits the `raise`.
#### Output of ``pd.show_versions()``

#### Code Sample, a copy-pastable example
```python
np.random.seed(0)
idx=pd.date_range('20000101','20201231',periods=50000)
df=pd.DataFrame(data=np.random.normal(0, 1, 50000),index=idx)
# exclude first 1000 to avoid un-primed periods
df.ewm(halflife=pd.Timedelta('10d'),times=df.index,adjust=True).mean().iloc[1000:].plot()
df.ewm(halflife=pd.Timedelta('10d'),times=df.index,adjust=False).mean().iloc[1000:].plot()
# Your code here
```
#### Problem description

#### Problem description
If I change column F's type to 'str' , everything goes well.
```python
In [11]:
df['F'] = df['F'].astype('str')
df['A']=df.groupby(['F'])['A'].transform(lambda x: x.fillna(x.mean()))
df
Out[11]:
A F
0 1.0 foo
1 3.0 nan
2 5.0 foo
3 5.0 foo
4 6.0 foo
5 8.0 foo
```

But, in that PR, we made use of `pandas.core.accessor.CachedAccessor`, which is how we add accessors in pandas under the hood:
https://github.com/pandas-dev/pandas/blob/ffa6e20d7dadd262d9035a647dffed9903fc5929/pandas/core/frame.py#L9730-L9731
So in GeoPandas we basically copied the above code, but with our adapted GeoPlotAccessor.
The reason that we can't use the public way to add accessors with `pd.api.extensions.register_dataframe_accessor` is that we are overriding an existing accessor of pandas (intentionally).
So can we consider `CachedAccessor` to be "public"-like so it is fine for GeoPandas to use it? Or do we want to explicitly expose the class in the `pandas.api.extensions` namespace? Or can we change `register_dataframe_accessor` to allow it to override existing methods? (not sure we want to make that too easy) | {

Task is to update the mypy pin in environment.yml and requirements-dev.txt, run `mypy pandas`, and then open a PR if it all passes (if it doesn't, please report back) | {

] | open | false | null | [] | null | 19 | 2021-02-27T16:37:31Z | 2021-08-19T01:31:46Z | null | MEMBER | null | In most contexts, Series is strict about dtype, so will always either return the given dtype or raise. DataFrame is the opposite, often silently ignoring dtype (xref #24435) (i think on the theory that dtype may be intended to apply to some columns but not others).
With floating data and integer dtypes, its the opposite:
```
arr = np.random.randn(5)
>>> pd.Series(arr, dtype="int16")
0 1.002695
1 0.259332
2 -1.111468
3 -0.680714
4 -0.008943
>>> pd.DataFrame(arr, dtype="int16")
0
0 1
1 0
2 -1
3 0
4 0
```
We have exactly one test that is broken if we change the latter behavior, and that is mostly by coincidence. There are other bugs (e.g. `Series(bigints, dtype="int8")` silently overflowing) that would be easier to fix if maintaining this behavior weren't a consideration.
Is this intentional? cc @jreback @jorisvandenbossche @TomAugspurger | {

vals = [
"nan",
pd.Timestamp("1990-01-01"),
"2015-03-14T16:15:14.123-08:00",
"2019-03-04T21:56:32.620-07:00",
None,
]
ser = pd.Series(vals)
```
As expected, this comes back as object-dtype, but it also does some casting:
```
>>> ser
0 NaT
1 1990-01-01 00:00:00
2 2015-03-14 16:15:14.123000-08:00
3 2019-03-04 21:56:32.620000-07:00
4 None
dtype: object
```
`ser[0]` is a _str_ "NaT" and `ser[[2, 3]]` are stdlib datetime objects. ser[1] and ser[4] are unchanged.
This casting is done inside a call to `to_datetime`, but has the surprising effect of not being idempotent:
```
>>> pd.to_datetime(ser)
ValueError: Tz-aware datetime.datetime cannot be converted to datetime64 unless utc=True
```
I'd expect `ser` to be constructed without doing any casting. | {
