BUG: is_bool_dtype 'Series' object has no attribute 'categories'

[Robbie-Palmer]

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

from pandas import Series
from pandas.core.dtypes.common import is_bool_dtype

s = Series(['foo', 'bar', 'baz'], dtype='category')
is_bool_dtype(s)

Issue Description

In pandas v1.3.0 the is_bool_dtype function returns False when passed a categorical Series
In pandas v1.4.0 it raises the error :

Traceback (most recent call last):
  File "./pandas/core/dtypes/common.py", line 1322, in is_bool_dtype
    arr_or_dtype = arr_or_dtype.categories
  File "./pandas/core/generic.py", line 5583, in __getattr__
    return object.__getattribute__(self, name)
AttributeError: 'Series' object has no attribute 'categories'

Expected Behavior

Expect is_bool_dtype to return False for categorical Series as happened in previous pandas versions

Hi @Robbie-Palmer, I would like to work on this issue. Can you give me more information about this bug?

[Robbie-Palmer]

Hi @anchal0997 I have already implemented a fix and put up a PR for it here: #45616

Does the above example not reproduce the error for you?

from pandas import Series
from pandas.core.dtypes.common import is_bool_dtype

s = Series(['foo', 'bar', 'baz'], dtype='category')
is_bool_dtype(s)

In pandas v1.3.0 the is_bool_dtype function returns False when passed a categorical Series
In pandas v1.4.0 it raises the error :
