When giving a string in the `subset` argument to dropna based on a single column, we get an error:
```
Index(...) must be called with a collection of some kind, 'C' was passed
```
#### Describe the solution you'd like
`DataFrame.dropna` should accept a single column subset as a string just like `DataFrame.drop_duplicates`
#### API breaking implications
None I could think of
```python
df = pd.DataFrame({"A": [1, 1, 3], "B": list("abc"), "C": [4, np.NaN, 5]})
print(df)
A B C
0 1 a 4.0
1 2 b NaN
2 3 c 5.0
df = df.dropna(subset="C")
print(df)
A B C
0 1 a 4.0
2 3 c 5.0
```

we can either use the fallback when `na` is specified or handle `na` in the array method, which may be more performant.
should we replicate StringArray:
```
>>> s = pd.Series(["Mouse", "dog", "house and parrot", "23", np.NaN], dtype="string")
>>>
>>> s.str.contains("og", na=3, regex=False)
0 False
1 True
2 False
3 False
4 True
dtype: boolean
>>>
>>> s.str.contains("og", na=np.nan, regex=False)
0 False
1 True
2 False
3 False
4 <NA>
dtype: boolean
>>>
```
or return an object array to preserve `na` if not pd.NA, True or False instead of coercing to bool/null? | {

The only solution I can find is [hiding the sheet manually with openpyxl](https://stackoverflow.com/questions/23157643/openpyxl-and-hidden-unhidden-excel-worksheets/23170772#23170772), but this is prohibitively slow for large files.
[My StackOverflow question on this](https://stackoverflow.com/questions/67154554/pandas-to-excel-with-sheets-being-hidden-or-efficiently-hiding-excel-tabs) is unanswered, which suggests I'm out of luck.
Testing openpyxl showed that we can't save .xlsxs without at least one visible tab, so it looks like this would only work like so:
```
writer = pd.ExcelWriter(filename, engine='xlsxwriter')
with writer:
df.to_excel(writer, sheet_name='df')
df.to_excel(writer, sheet_name='2nd tab')
```
Would adding `hidden=True` to `to_excel` be practical?

[errorbar visualization](https://pandas.pydata.org/pandas-docs/stable/user_guide/visualization.html#plotting-with-error-bars)
#### Documentation problem
Currently there's only an example of the symmetrical case, i.e. where the lower/upper errors are the same. The asymmetrical case is supported but actually quite tricky to get to work. I could only find one [stackoverflow post](https://stackoverflow.com/questions/45798492/asymmetrical-errorbar-with-pandas) and it is not especially helpful
#### Suggested fix for documentation
I suggest adding an example that showcases how to plot asymmetrical errorbars

I am struggling in assigning new columns in my data frame, based on existing columns in the same data frame.
I keep getting this SettingWithCopyWarning that is driving me crazy:
_C:\ProgramData\Anaconda3\envs\PLAXIS_V20.3_python37\lib\site-packages\pandas\core\indexing.py:1596: SettingWithCopyWarning:
A value is trying to be set on a copy of a slice from a DataFrame.
Try using .loc[row_indexer,col_indexer] = value instead
See the caveats in the documentation: https://pandas.pydata.org/pandas-docs/stable/user_guide/indexing.html#returning-a-view-versus-a-copy
self.obj[key] = _infer_fill_value(value)
C:\ProgramData\Anaconda3\envs\PLAXIS_V20.3_python37\lib\site-packages\pandas\core\indexing.py:1783: SettingWithCopyWarning:
A value is trying to be set on a copy of a slice from a DataFrame.
Try using .loc[row_indexer,col_indexer] = value instead
See the caveats in the documentation: https://pandas.pydata.org/pandas-docs/stable/user_guide/indexing.html#returning-a-view-versus-a-copy
self.obj[item_labels[indexer[info_axis]]] = value_
The code that I am trying to run is the following:
__dfe = df_sampled.loc[mask]
af=dfe["Dist_{}_{}_UKPN_ mm".format(i,j)]
af.apply(lambda x: ((x*0.001)/ref)*100)
dfe.loc[:,"Dist_{}_{}_UKPN_ perc".format(i,j)]=af
My goal is to create a new column on the dfe dataframe ( which is a sub dataframe from another dataframe), which is based on the existing column on the dfe, but multiple by scalars values ( e.g to convert them into percentage)
I hope someone can help to understand how to overcome this
Thanks

Sometimes, one would like to get a column regardless whether it was previously set as index.
Consider the following example:
```python
df = pd.DataFrame(np.arange(50).reshape(5,10).T, columns=list("ABCDE"))
df = df.set_index(["A","B"])
col = df.get("B")
```
In the above code `col` is set to `None`.
## Solution
I suggest to add an argument `include_index`, so that the following is possible:
```python
item = df.get("B", include_index=True)
```
It first checks the column names, and if not successful, continues searching the index names. It still returns None if no item was found.
This permits simpler queries that combine indices and columns:
```python
mask = (df.get("B", include_index=True) > 15) & (df.get("C", include_index=True) > 20)
```
## Implications on API
Backwards compatibility is guaranteed by setting the default value of `include_index=False`.
The return type of `get(key, include_index=True)` is now Optional[Union[pd.Series, pd.Index]]. If `key` belongs to the index, a `pd.Index` must be returned. A conversion to `pd.Series` is infeasible.
## Alternatives
Currently, the idiomatic way to return either column or index is:
```python
def get_item(df, key):
return df[key] if key in df else (df.index.get_level_values(key) if key in df.index.names else None)
```

import pandas as pd
df = pd.DataFrame({"string": pd.array([], dtype="string")})
table = pa.Table.from_pandas(df)
print(table.column(0))
# <pyarrow.lib.ChunkedArray object at 0x12c5cec70>
# [
# []
# ]
# Construct a Table with zero chunks as returned by `pyarrow.dataset`
empty_table = pa.table([pa.chunked_array([], type=pa.string())], schema=table.schema)
print(empty_table.column(0))
# <pyarrow.lib.ChunkedArray object at 0x12c5cee00>
# [

#### Problem description
The problem here is that we are checking in `_concat_same_type` whether we concat arrays of the same type but as we don't concatenate anything, there are also no types to check. This should instead create an empty array. | {

Attempting an approach to fix this. Let's see if it works.
Not surprisingly, the bruteforce approach breaks a bunch of stuff, because I ended up with twice the utcoffset shift instead of once, which makes perfect sense.
What we want here instead is to get the first valid nanosecond of the day by default and normalize to that. And probably expose to the user the ability to shift back for normalization if midnight does not exist.
Will try to fix this tomorrow. | {

#### Code Sample, a copy-pastable example
```python
import pandas as pd
dfo = pd.DataFrame({"A": ["abc", "def"], "B": ["ghi", "jkl"]}, dtype="object")
dfs = pd.DataFrame({"A": ["abc", "def"], "B": ["ghi", "jkl"]}, dtype="string")
dfo.loc[0, :] = {"A": "newA", "B": "newB"}
dfs.loc[0, :] = {"A": "newA", "B": "newB"}
print(dfo)
# Output:
# A B
# 0 newA newB
# 1 def jkl
print(dfs)
# Output:
# A B
# 0 A B
# 1 def jkl
```
#### Problem description
The interpretation of the RHS_dict depends on the dtype of the dataframe assigned to:
Assigning to an object-dataframe: Interpretation as ``pd.Series(RHS_dict)``
Assigning to a string-dataframe: Interpretation as ``list(RHS_dict)``
This is inconsistent and unexpected.
In my script I started with an object-dataframe and later changed to a string-dataframe. This change led to an incorrect result, due to the effect desribed above.
#### Expected Output
The interpretation of the RHS_dict does NOT depend on the dtype of the dataframe asigned to.
Personally I'd prefer ``pd.Series(RHS_dict)``, but if wiser men than me decide that ``list(RHS_dict)`` is correct, I won't object, as long as the behaviour is consistent across dtypes.

- [x] closes #40896
- [x] tests added / passed
- [x] Ensure all linting tests pass, see [here](https://pandas.pydata.org/pandas-docs/dev/development/contributing.html#code-standards) for how to run them
- [x] whatsnew entry
Points I'm not sure about:
- I created a new test file. Would it be better to place the test somewhere else?
- The test only tests int32. Should I add more dtypes?
I'm still new to the internals of pandas and always trying to improve so feedback of any kind is highly appreciated! | {

#### Code Sample, a copy-pastable example
```python
dates = ['2020-05-01T18:04:03Z', '2020-04-28T17:54:06Z', '2020-04-26T18:04:09Z']
print(pd.to_datetime(dates, infer_datetime_format=True)) #drops UTC

dates = ['2020-05-01T18:04:03.0Z', '2020-04-28T17:54:06.0Z', '2020-04-26T18:04:09.0Z']
print(pd.to_datetime(dates, infer_datetime_format=True)) #works!
```
Output:
```
DatetimeIndex(['2020-05-01 18:04:03', '2020-04-28 17:54:06',
'2020-04-26 18:04:09'],
dtype='datetime64[ns]', freq=None)
DatetimeIndex(['2020-05-01 18:04:03+00:00', '2020-04-28 17:54:06+00:00',
'2020-04-26 18:04:09+00:00'],
dtype='datetime64[ns, UTC]', freq=None)
DatetimeIndex(['2020-05-01 18:04:03+00:00', '2020-04-28 17:54:06+00:00',
'2020-04-26 18:04:09+00:00'],
dtype='datetime64[ns, UTC]', freq=None)
```
#### Problem description
Using infer_datetime_format=True drops the timezone info (UTC) if datestrings do not have decimal seconds as shown in the example above. '2020-05-01T18:04:03Z' is a valid ISO 8601 datetime (https://tools.ietf.org/html/rfc3339#section-5.6).
#### Expected Output
```
dates = ['2020-05-01T18:04:03Z', '2020-04-28T17:54:06Z', '2020-04-26T18:04:09Z']
print(pd.to_datetime(dates, infer_datetime_format=True))
#DatetimeIndex(['2020-05-01 18:04:03+00:00', '2020-04-28 17:54:06+00:00',
# '2020-04-26 18:04:09+00:00'],
# dtype='datetime64[ns, UTC]', freq=None)

#### Code Sample, a copy-pastable example
```python
tmp = pd.DataFrame(
[
0.03,
0.03,
0.001,
np.NaN,
0.002,
0.008,
np.NaN,
np.NaN,
np.NaN,
np.NaN,
np.NaN,
np.NaN,
0.005,
0.2
]
)
tmp.iloc[1:].rolling(5, min_periods=0).mean() # Returns 0 at indexes 10 and 11
tmp.iloc[2:].rolling(5, min_periods=0).mean() # Returns np.NaN at indexes 10 and 11
```
#### Problem description
Pandas rolling mean computation inconsistently treats windows with NaN values only, depending on how far they are in the DataFrame. Here we can see how the values for the windows indexed as 10 and 11 are set to 0 or NaN depending on whether we start the computation starting from the 2nd observation or the 3rd.
Other aggregation functions (like sum) don't seem to suffer from this
This only happens when min_periods is set to 0
This doesn't happen in pandas version 1.0.3
This doesn't happen if non NaN values are set to 1 instead of floating values
This could be linked to another reported issue that I haven't identified after a quick search
#### Expected Output
The expected output would be for the mean computation to return np.NaN for the indexes 10 and 11 in both cases, consistent with pandas documentation and other aggregation functions behavior
#### Output of ``pd.show_versions()``

```
#### Problem description
pandas is unable to copy from the clipboard on windows using wsl2. This affects workflows where data is copied between spreadsheets, from the web and a dataframe is created, or vice-versa (i.e. dataframe is copied into a spreadsheet).
Pandas ships a vendored version of pyperclip that is old. The recent version of pyperclip resolves this issue on windows wsl2 in this pull request. https://github.com/asweigart/pyperclip/pull/168
As can be seen in my pasted code sample, I have the most recent pyperclip installed on my system, and the clipboard functionality works as expected.
We can fix pandas' clipboard functionality by updating the vendored code (it seems that copy-pasting the `__init__.py` file from pyperclip ought to do the trick.
I'd be happy to contribute this change if the issue is approved. There seems to be a separate effort to move the backend from pyperclip to pyclip
#### Expected Output
I would expect to see
#### Output of ``pd.show_versions()``

#### Code Sample, a copy-pastable example
```python
import pandas as pd
str_obj_ser = pd.Series(["1", "2", "3", None], dtype="object")
mix_obj_ser = pd.Series([1, "2", 3.0, None], dtype="object")
num_obj_ser = pd.Series([1, 2, 3.0, None], dtype="object")
str_obj_ser.astype("Int16") # Exception
mix_obj_ser.astype("Int16") # different Exception
num_obj_ser.astype("Int16") # works
str_obj_ser.astype("string").astype("Int16") # works
mix_obj_ser.astype("string").astype("Int16") # Exception
num_obj_ser.astype("string").astype("Int16") # Exception
str_obj_ser.astype("string").astype("Float64").astype("Int16") # works
mix_obj_ser.astype("string").astype("Float64").astype("Int16") # works
num_obj_ser.astype("string").astype("Float64").astype("Int16") # works
str_obj_ser.astype("Float64").astype("Int16") # Exception
mix_obj_ser.astype("Float64").astype("Int16") # works
num_obj_ser.astype("Float64").astype("Int16") # works
```
#### Problem description
The conversion of an object-series with some text in it to one of the nullable integer dtypes fails even though all elements of the series are convertable to integers (or to pd.NA).
This issue seems to be related to #40729, but the workaround described there for Floatxx doesn't work in all cases here:
The detour via dtype string is not evough if an element in the object-series is a float because int("3.0") doesn't work (but int(3.0) does). A detour via string and then Float64 is necessary for all examples given above to work (for some cases, but not all, the string step can be omitted).
But even the detour via string and Float64 to Int16 is not guaranteed to always work, e.g. if an element of the series is an object with an ``__int__()`` method (returning a number) and a ``__str__()`` method (returning a description, not an integer literal).
I think the topic of this issue has also been mentioned in the discussion of #39616.
#### Expected Output
The conversion of a series of dtype object to one of the nullable integer dtypes should always work if all elements of the series are convertable to the target dtype.
At least something along the lines of
* element is None, pd.NA, np.nan, ... -> pd.NA
* otherwise -> int(element)
I'd even prefer something like
* element is None, pd.NA, np.nan, ... -> pd.NA
* element is string, bytes or bytearray -> int(element, 0)
* otherwise -> int(element)
such that string literals like "0x7f" work.
As the latter doesn't work with the current string -> Int16 conversion though, that would be more like an enhancement than a bugfix.

#### Code Sample, a copy-pastable example
```python
import pandas as pd
k = frozenset(["KEY"])
df1 = pd.DataFrame([[1,2,3,4], [5,6,7,8]], columns=[k, "B", "C", "D"])
df2 = pd.DataFrame([[1,2,3,4], [5,6,7,8]], columns=[k, "B", "C", "C"])
print(df1[k]) # works
print(df2[k]) # KeyError: "None of [Index(['KEY'], dtype='object')] are in the [columns]"
```
#### Problem description
Indexing a dataframe with a frozenset raises a KeyError if column names are not unique (the name of the indexed column is unique):
```python-traceback
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\test\venv124\lib\site-packages\pandas\core\frame.py", line 3030, in __getitem__
indexer = self.loc._get_listlike_indexer(key, axis=1, raise_missing=True)[1]
File "C:\test\venv124\lib\site-packages\pandas\core\indexing.py", line 1266, in _get_listlike_indexer
self._validate_read_indexer(keyarr, indexer, axis, raise_missing=raise_missing)
File "C:\test\venv124\lib\site-packages\pandas\core\indexing.py", line 1308, in _validate_read_indexer
raise KeyError(f"None of [{key}] are in the [{axis_name}]")
KeyError: "None of [Index(['KEY'], dtype='object')] are in the [columns]"
```
Indexing another dataframe that only differs by having unique column names works, so using a frozenset as column name seems to be ok.
The traceback seems to indicate that a "listlike_indexer" is involved - maybe with non-unique column names a different indexer is used that has problems with non-atomic column names, turning the column name ``frozenset(["KEY"])`` into ``"KEY"``. Just a guess based on the error message, I don't know anything about how pandas indexers work.
#### Expected Output
Indexing works with a column name of arbitrary type regardless of whether the other column names are unique or not.

#### Question about pandas
I have a DataFrame with a time series as index.
import pandas as pd
from numpy.random import rand
df = pd.DataFrame(rand(100000), index=None, columns=['a'])
df['time'] = pd.date_range('2020-01-01 12:30:15',
periods=len(df['a']), freq='ms')
df.set_index('time', inplace=True)
df.plot()
When I put a multiplier on the frequency, it becomes extremely slow to plot `df2`, even if it has less elements than `df`. It actually crashed my Python kernel, and my laptop almost ran out of RAM
df2 = pd.DataFrame(rand(50000), index=None, columns=['a'])
df2['time'] = pd.date_range('2020-01-01 12:30:15',
periods=len(df2['a']), freq='2.5ms')
df2.set_index('time', inplace=True)
df2.plot()
Trying with `freq=2500U` does not make any difference
I was wondering if this behavior is normal. Haven't tried to run this on a code profiler. Or with any other algorithms, to see if has any effect.
Thanks

df = pd.DataFrame.from_dict({1:'Single line', 2:'Multiline \n with bkslash_N', 3:'Multiline \r with bkslash_R'}, orient="index", columns=['text'])
df.to_csv()
',0\n1,Single line\n2,"Multiline \n with bkslash_N"\n3,Multiline \r with bkslash_R\n'
```
No quotes on line 3
#### Problem description
When text has '\r' as a line separator, `pandas.to_csv()` does not consider such text as multiline and does not surround it with quotes. As a result such CSV files are incompatible other parsers.
#### Expected Output
The text around "Multiline \r with bkslash_R" should be quoted
```
',0\n1,Single line\n2,"Multiline \n with bkslash_N"\n3,"Multiline \r with bkslash_R"\n'
```

#### Code Sample, a copy-pastable example
```python
import pathlib
import sys
import pandas
text = """I am able.
One powerful way.
"Trouble concentrating, television?"
"Maybe, or. You and family, or your best work."
assessment!
more about them and help.
"The more you say, the better I'll be"
"""
file_name = "boo.csv"
pathlib.Path(file_name).write_text(text)
pandas.read_csv(file_name, names=("text",))
print("Works!")
sys.setprofile(lambda *a, **k: None)
print("And it's broken...")
pandas.read_csv(file_name, names=("text",))
```
#### Problem description
`Pandas.read_csv` breaks if I run `sys.setprofile(lambda *a, **k: None)`...
```bash
Works!
And it's broken...

I don't know why but when I delete venv folder and create a new venv and install pandas again, it automatically resolves but after 3-4 days, it throws an error about importing NumPy. There isn't a problem with the NumPy version because I don't manually install NumPy or any package with NumPy dependency before installing pandas. Anyway, I don't use another package using Numpy.

Pandas DataFrame formatters have similar logic but noyt identical and are applied in different ways: For example:
- FloatArrayFormatter doesn't have the thousands argument which is quite useful for Europeans.
- the FloatArrayFormatter is vectorised but Styler does display_funcs element-wise (which it can't avoid for processing individual cell styles). This may make it difficult to refactor across module (unless the fomat_class was called element-wise)
- it is difficult to replicate other parameters such as the escape_html (escape_latex) arguments in the same processing order to preserve features and the subset argument makes vectorisation difficult, in addition to item 2.

- [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
ts = pd.Timestamp(year=2001, month=10, day=14, hour=0, minute=30, tz='America/Santiago')
print(ts)
```
#### Problem description
There was a [DST transition](https://www.timeanddate.com/time/change/chile/santiago?year=2001) on the 14th of October 2001, and the time from midnight to 1 a.m. does not exist. Ran into this while working on #40517 where we ran into an error while normalizing a `Timestamp` when midnight does not exist in a particular timezone. Yet, we are able to create this timestamp directly, even though it does not make any sense.
#### Expected Output
I would expect `NonExistentTimeError: 2001-10-14 00:30:00`
#### Notes
I wasn't able to find a prior issue for this. I'm a bit swamped right now, so I would appreciate if someone else looked at this bug. If no one takes it up, I'll investigate next week.
#### Output of ``pd.show_versions()``
<details>
This is on my dev environment, but I'm getting the same behavior on the latest stable version.

**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
pdf = pandas.DataFrame([1, 'a', True])
# behavior for pandas 1.2.3
pdf.prod(axis=0, min_count=1, numeric_only=False)
0 a
dtype: object
# behavior for pandas 1.2.4
pdf.prod(axis=0, min_count=1, numeric_only=False)
AssertionError: assert numeric_only is None
# behavior for pandas 1.2.3
pdf.sum(axis=0, min_count=1, numeric_only=False)
TypeError: unsupported operand type(s) for +: 'int' and 'str'
# behavior for pandas 1.2.4
pdf.sum(axis=0, min_count=1, numeric_only=False)
AssertionError: assert numeric_only is None
```
#### Problem description
Some of the reduction operations (namely, `sum` and `prod`) has changed own behavior in 1.2.4 comparing to 1.2.3. `prod` has become failing and `sum` has thrown another exception. Other reduction operations need to be checked as well.

This already enables most of the JSON tests (it are only the table schema tests that are segfaulting). Those are mostly working because the JSON writer falls back to using `df.values`. This only gives some errors with datetime formatting, for which one test is skipped (and this will then be fixed by letting the JSON code work column-by-column) | {

Hi there, my understanding of the df.groupby.rolling for a multi index dataframe should preserve the level-1 index, but I can't seem to get that. I am running Pandas 1.2.4. Hope that somebody can provide some insight of what is happening
```python
x = range(0, 6)
id = ['a', 'a', 'a', 'b', 'b', 'b']
temp = pd.DataFrame(zip(id, x), columns = ['id', 'x'])
temp['sequence']=[0,1,2,0,1,2]
temp=temp.set_index(['id','sequence'])
print(temp)
x
id sequence
a 0 0
1 1
2 2
b 0 3
1 4
2 5
temp.groupby(level=0,group_keys=True).rolling(2, min_periods=1).min()
x
id
a 0.0
a 0.0
a 1.0
b 3.0
b 3.0
b 4.0
```
base don the online guides, I would expect the level 1 index to be preserved...but I can't understand what is currently happening at this case? or what is the correct way of doing it.
Hope that somebody can provide some insights with regards to this problem
EDIT: Edited as text for readability, apologies for posting images earlier, forgot about it while posting it just now

I'm familiar with several issues being reported relating to skipna=False, but I have not seen this particular problem elsewhere. In short, the 'skipna=False' setting causes errors in rows not having any missing values.
#### Code Sample, a copy-pastable example
```python
# Minimal code to reproduce in pandas 1.2.4:
import pandas as pd
df1 = pd.DataFrame({"A": [False,pd.NA,pd.NA], "B": [True,True,False]})
df1
A B
0 False True
1 <NA> True
2 <NA> False
df1.all(axis=1, skipna=False)
0 True
1 True
2 False
dtype: bool
# And again with experimental BooleanDtype
df2 = pd.DataFrame({"A": [False,pd.NA,pd.NA], "B": [True,True,False]}, dtype=pd.BooleanDtype())
df2
A B
0 False True
1 <NA> True
2 <NA> False
df2.all(axis=1, skipna=False)
0 True
1 True
2 True
dtype: bool
```
#### Problem description
With df1 row '0' is clearly wrong; with df2 '0' and '2' are undeniably wrong. The rest are imho also suspicious, but they at least follow the documented behavior of:
> If skipna is False, then NA are treated as True, because these are not equal to zero.
...even if I do believe the mathematically correct answers are as given e.g. here:
https://www.ibm.com/docs/en/spss-statistics/SaaS?topic=command-missing-values-logical-operators-if
In other words, row '1' should, imho, evaluate to 'NA'.
#### Expected Output
Rows '0' and '2' should clearly evaluate to 'False'.
Row '1' should maybe evaluate to 'NA'.

I'm a huge fan on pandas, but I primarily use vtkf files (.vti mostly) and analyse them in Paraview. I hate paraview, and would much rather use pandas, so was wondering if there's any way to include the capabilities of something like vtkf explorer within pandas to allow people to read in vtk files as dataframes

This is a small refactor of the JSON writing code (`objToJSON.c`) to remove the access of the Blocks. Serializing to JSON was already done column-by-column (also when accessing the blocks), but currently we were iterating over the different "columns" of the 2D array per block in the C code. While with this PR, the C code directly iterates over all the columns (instead of per block).
This gives a less invasive change as the previous attempt of https://github.com/pandas-dev/pandas/pull/27166
To be able to iterate over the column arrays in C, I added the `column_arrays` attribute on the manager, for this.
I ran the JSON ASV benchmarks with this branch:
`$ asv continuous -b json -f 1.01 upstream/master HEAD`

There is a slight slowdown in some of the benchmarks for wide dataframes, but only 20%.
So we can decide to keep the original block-iteration code for BlockManager for now, instead of fully replacing it as I did now, if we don't want this slight slowdown.
This also fixes some remaining cases for ArrayManager (xref https://github.com/pandas-dev/pandas/issues/39146) | {

`str.rsplit` can probably also be added to this PR (the tests are parameterised, one failing for StringArray.. maybe precursor needed)
also issue with empty string

I could be convinced that this is worth supporting, but it shouldn't be shoehorned into `SeriesGroupBy.aggregate` the way it is.
AFAICT this is not documented, supports only one test (parametrized over 4 dtypes):
```
@pytest.mark.parametrize("dtype", ["int64", "int32", "float64", "float32"])
def test_basic(dtype):
data = pd.Series(np.arange(9) // 3, index=np.arange(9), dtype=dtype)
index = np.arange(9)
np.random.shuffle(index)
data = data.reindex(index)
grouped = data.groupby(lambda x: x // 3)
[...]
group_constants = {0: 10, 1: 20, 2: 30}
agged = grouped.agg(lambda x: group_constants[x.name] + x.mean())
assert agged[1] == 21

A time to talk about pandas documentation. [Agenda/notes doc](https://docs.google.com/document/d/1JoiqTdK6gi5W1QiTWrqtTV-rNmIqU3xROgHY5iT4J5g/edit#heading=h.snd8dmkwtkdi) — feel free to add things in advance. All are welcome. Sorry for the late reminder. Hope to see you there!

I cannot create DataFrames based on SQL view tables:
```
sqlalchemy.exc.InvalidRequestError: Could not reflect: requested table(s) not available in Engine(...) schema 'ml_dataset': (dataset)
```
#### Describe the solution you'd like
It would be great to be able to read views. `SELECT * FROM table;` does not behave differently if `table` is a table, a view, a materialized view or a foreign table.
#### API breaking implications
No backward compatible changes.
#### Describe alternatives you've considered
Instead of extending `read_sql_table` a new function could be created, like `read_sql_view`
#### Additional context
Workaround:
```python
df = pandas.read_sql_query("select * from sampletable", viltkamera_postgres)
```

It is now pinned to Python 3.8 (https://github.com/pandas-dev/pandas/pull/41092), but we should fix the warning for Python 3.9, and unpin the environment.

My concrete example would be something like `(A % 3) == 0`. Unfortunately, this kind of conditions does not seem to be possible in the current implementation, although https://www.pytables.org/usersguide/condition_syntax.html seems to suggest otherwise.
#### Code Sample
```python
import numpy as np
import pandas as pd
df = pd.DataFrame({'A': np.arange(0, 10)})
with pd.HDFStore('test.h5') as s:
s.put("test", df, format='t', data_columns=['A'])
print(s.select("test", where=["(A % 3) == 0"])
```
#### Problem Description
The condition fails to parse. It seems that the `A % 3` is interpreted as a boolean expression which obviously fails. Especially when loading the whole table into memory is not an option, filtering via such arithmetic expressions should be possible. PyTables seems to support this already, but it doesn't work in pandas.
```

This gives 1) faster CI feedback for doc PRs, 2) less chance on unrelated (flaky) failures on such PRs, and 3) in general reduces the CI load.
For the github actions, there is a `on.paths` option to do this, and it actually supports the "exclude paths" feature that we need: https://docs.github.com/en/actions/reference/workflow-syntax-for-github-actions#example-ignoring-paths
For the Azure builds, it seems this might also be possible: https://docs.microsoft.com/en-us/azure/devops/pipelines/repos/azure-repos-git?view=azure-devops&tabs=yaml#paths

I was looking into getting rid of the Block fallback (`apply_with_block`) for `fillna` in ArrayManager. For that, I started with putting the bits and pieces from the several BlockManager methods (the different `fillna` implementations, maybe_downcast) together in a function that would do the same for plain arrays as input, to see what this would give.
The draft result of that can be seen in this PR. This seems to pass all tests for the ArrayManager, so should have the same behaviour as BlockManager.fillna. I only hoped that we could then also use this in the BlockManager to have a shared implementation (as we did for eg `Block.astype` and others). However, that doesn't seem so easy in this case .. So not yet sure how to best proceed here. | {

According to https://docs.python.org/3/library/functions.html#locals, `locals()` should not be modified. AFAICT these are the only places `locals()` is used in this way without copying. | {

The problem is not numerical stable, so we are dividing -3e-18 / 0, which returns -inf running into line 177 setting to 0. Checking for nobs > 0 would solve these cases

#### Code Sample, a copy-pastable example
copy this text, or data from excel/libreoffice with the same shape
```
col1 col2
1 red
blue
2 green
```
```python
In [3]: pandas.read_clipboard()
Out[3]:
col1 col2
0 1 red
1 blue None
2 2 green
```
#### Problem description
Using read_clipboard() on excel data when there are null values on the first few rows of the first columns causes pandas to use the default separator instead of the "\t" used for excel.
The result is the values shift into the wrong column
#### Expected Output
```python
In [4]: pandas.read_clipboard()
Out[4]:
col1 col2
0 1.0 red
1 NaN blue
2 2.0 green
```
#### Output of ``pd.show_versions()``

Stripping whitespace on read_clipboard causes data copied from
excel to lose the tab separator between the first column and
the nexts, shifting the data into the wrong column
This just removes the .lstrip() except for the first line
containing headers, to avoid breaking header-less index in csv
files
- [x] closes #41108
- [x] tests added / passed
- [x] Ensure all linting tests pass, see [here](https://pandas.pydata.org/pandas-docs/dev/development/contributing.html#code-standards) for how to run them

- .agg should always reduce #35725
- Series.transform and DataFrame.transform should broadcast reduces (like groupby does) #18103
- Series.apply and DataFrame.apply use agg for list/dict arguments
- Series.agg and DataFrame.agg use apply if argument is a UDF
- UDF method arguments are inconsistent #40112
- Make groupby.apply dumb #39209
- groupby.apply includes grouping column(s) in computation unlike groupby.agg/groupby.transform
- Series.agg and DataFrame.agg don't allow partial failure when TypeError is raised #40539
- Ban mutation from UDF methods #12653
For some of these, it is difficult to emit a FutureWarning. For example, I'm not sure how we would emit a warning changing the behavior of agg for UDFs. I've been working toward consolidating the methods for apply/agg/transform et al in `pandas.core.apply`, resolving consistencies as they are encountered. This is very much a work in progress, and I expect to encounter more.
In order to make better progress here, I'd like to work on a new, experimental, implementation behind an option similar to ArrayManager. Progress can then be made without worrying about deprecation warnings and changing behaviors. When it's ready, we can then progress as:
- Add docs on the option and users can opt-in.
- Change the default of the option to no-default, emitting a FutureWarning when not set that the behavior of many methods will change and that users should use the new implementation.
- Change the default of the option to the new implementation, keeping the option to allow users to change back if necessary.
- Remove the option and old implementation. | {

The sticking point that makes this not-a-slam-dunk is that a [check](https://github.com/pandas-dev/pandas/compare/master...jbrockmendel:ref-gbop-wrapped?expand=1#diff-17420aa54e4b74826eaaeedc6ef6b320c16691aa74c09420e6098854284b4874L833-L835) is removed:
```
if self._filter_empty_groups and not counts.all():
assert result.ndim != 2
result = result[counts > 0]
```
This condition never holds in the tests, and the assertion would fail if it ever did. I don't have a compelling reason to remove this check other than it being inconvenient to move it to WrappedCythonOp. | {

Hi,
I'm trying to use json_normalize to flatten a complex dictionary where there are nestes dict and nested list. While the record_path accepts a list of strings, the record_prefix only accepts a single string, this does not allow me to set a different prefix in corresponding to each element in record_path. Can we allow record_prefix to be a list?
Thanks

#### Code Sample
*data.csv*
> key,value
> a,1.234
> b,"1,234.00"
> c,":"
Reading the data works ok without parsing the numbers
```python
>>> pd.read_csv('data.csv')
key value
0 a 1.234
1 b 1,234.00
2 c :
```
When parsing numbers it fails even when the correct thousand separator is set:
```python
>>> pd.read_csv('data.csv', dtype={'value': float}, thousands=',')
ValueError: could not convert string to float: '1,234.00'
```
However, with the right N/A value setting it works
```python
pd.read_csv('data.csv', dtype={'value': float}, thousands=',', na_values=':')
key value
0 a 1.234
1 b 1234.000
2 c NaN
```
#### Problem description
I think the error message saying that pandas could not convert value "1,234.00" to a number is uninformative as the error is rather in the missing value ":".
Might be related to #2570.
#### Expected Output
I’d expect the error message should be about the non-parsable value ":".
#### Output of ``pd.show_versions()``

#### Code Sample, a copy-pastable example
```python
# Your code here
import pandas as pd
df = pd.DataFrame(data=[
{"a": 1, "b": None},
{"a": 2, "b": None},
])
df.groupby(["a", "b"]).size() # returns Series([], dtype: int64)
df.drop_duplicates() # returns the dataframe itself
```
#### Problem description
The 2 rows in my dataframe are different and grouping on the 2 columns should thus not return an empty `Series`.
Update: I observe the same behavior when I use np.nan` instead of `None`
#### Expected Output
```
a b
1 None 1
2 None 1
dtype: int64
```
#### Output of ``pd.show_versions()``
