Guido van Rossum <gu...@python.org> added the comment:
It never occurred to me that making b&b an b|b return bool would be considered a bad thing just because ~b is not a bool. That's like complaining that 1+1 returns an int rather than a float for consistency with 1/2 returning a float. Because bool is embedded in int, it's okay to return a bool value *that compares equal to the int from the corresponding int operation*. Code that accepts ints and is passed bools will continue to work. But if we were to make ~b return `not b`, that makes bool not embedded in int (for the sake of numeric operations). Take for example def f(a: int) -> int: return ~a I don't think it's a good idea to make f(0) != f(False). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue37831> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
