pandas (original) (raw)

Pandas version checks

I have checked that this issue has not already been reported.
I have confirmed this bug exists on the latest version of pandas.
I have confirmed this bug exists on the main branch of pandas.

Reproducible Example

df = pd.DataFrame({"A": pd.Series([1,2,3], dtype=pd.ArrowDtype(pa.int8())), "B": pd.Series([1,2,3], dtype=pd.ArrowDtype(pa.int16()))}) df.describe(include=pd.ArrowDtype(pa.int8())) A B count 3.0 3.0 mean 2.0 2.0 std 1.0 1.0 min 1.0 1.0 25% 1.5 1.5 50% 2.0 2.0 75% 2.5 2.5 max 3.0 3.0

Issue Description

Only describe for column "A" should have been calculated, because it's the only int8 column in the dataframe.

Expected Behavior

Expected behavior is behavior with numpy types:

>>> df = pd.DataFrame({"A": pd.Series([1,2,3], dtype=np.dtype("int8")), "B": pd.Series([1,2,3], dtype=np.dtype("int16"))})
>>> df.describe(include=np.dtype("int8"))
         A
count  3.0
mean   2.0
std    1.0
min    1.0
25%    1.5
50%    2.0
75%    2.5
max    3.0
>>>

This only calculates describe for column "A".
