Tim Peters added the comment: Victor, this part of the docs explains what you're seeing; scroll down to the
""" In enforcing reflexivity of elements, the comparison of collections assumes that for a collection element x, x == x is always true ... """ part. https://docs.python.org/3/reference/expressions.html#value-comparisons In passing, note that dicts indexed by strings (well, indexed by anything) _do_ compare hashes first. In that specific case it's a major win - but in that specific case we also know in advance that "EQ or NE?" is the only question needing an answer. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue30907> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
