There was a problem hiding this comment.
can you move to pandas/util/validators.py
shouldn't this raise for a list-like case if something is wrong?

e.g. this shouldn't return anything
pls add some typing

It raises for a list-like case if any of the items in ascending list is not treated as a valid boolean.
This construct does just that.
return [validate_bool_kwarg(item, "ascending", **kwargs) for item in ascending]

this can simply be part of validate_bool_kwarg or another function but should be co-located with validate_bool_kwarg

Moved the function to pandas/util/_validators.py.
It is not clear for me at the moment how to make this validation anyhow different (as a part of validate_bool_kwarg) due to the fact that multiple types are acceptable for ascending.

can you make these lists

and maybe add an empty list too

Currently an empty list does not raise an error, so the test fails.
Should I change the code, so that an empty list raises?
