There was a problem hiding this comment.
I think names: Sequence[Level | None] | lib.NoDefault or similar as the docstring is under-specifying what can be accepted here (more than just strings)
In [1]: >>> numbers = [0, 1, 2]
...: >>> colors = ['green', 'purple']
...: >>> pd.MultiIndex.from_product([numbers, colors],
...: ... names=[55, 60])
Out[1]:
MultiIndex([(0, 'green'),
(0, 'purple'),
(1, 'green'),
(1, 'purple'),
(2, 'green'),
(2, 'purple')],
names=[55, 60])

There are (unsurprisingly) many errors when trying to use pyright/mypy to validate pandas-stub's tests against the pandas annotations. This PR fixes three of them.
