In docstring of Set._hash in _collections_abc.py is written:
"We match the algorithm used by the built-in frozenset type."
But
>>> s = frozenset({i for i in range(10)})
>>> hash(s)
3895031357313128696
>>> Set._hash(s)
3914343279946282847
Looks like Set._hash is different.

I opened a PR. It looks like frozenset.__hash__ changed in GH-5194 and GH-5235, but Set._hash wasn't updated accordingly. |
