Rémi Lapeyre <remi.lape...@henki.fr> added the comment: The set is converted to a frozenset before the comparison so
>>> {1,2} in {frozenset({1,2}), 3} is equivalent to >>> frozenset({1,2}) in {frozenset({1,2}), 3} This was introduced on purpose 17 years ago in 19c2d778 so it's unlikely to change. ---------- nosy: +remi.lapeyre _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue40853> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
