.iloc
fails #48188doc/source/whatsnew/vX.X.X.rst
file if fixing a bug or adding a new feature.This patch makes tuple subclasses behave the same as tuple in
df.iloc[key]
anddf.loc[key]
. All but one of the tests pass. The failing test (indexing/test_loc.py::TestLocBaseIndependent::test_loc_getitem_index_namedtuple
) raises an exception ondf.loc[key]
(not.iloc
). I've opened issue #50597 where I suggest deprecating the behavior in that test. This patch would enforce that deprecation in addition to closing #48188.I'm opening this as is WIP but please comment. I have doubts on whether I'm on the right track with this.
