>From https://docs.python.org/3/reference/datamodel.html#object.__hash__ User-defined classes have __eq__() and __hash__() methods by default; with them, all objects compare unequal (except with themselves) and x.__hash__() returns an appropriate value such that x == y implies both that x is y and hash(x) == hash(y). It doesn't work like that for tuples, NamedTuples nor dataclasses because their behaviour isn't expected to be a "user-defined class". ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue46739> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
