New submission from Alex Waygood <alex.wayg...@gmail.com>:
Attempting to create an enum with __slots__ silently fails. No error is raised if __slots__ are specified, but the usual behaviour of __slots__ does not work as expected. Attributes that are not specified in __slots__ can be freely set: >>> from enum import Enum >>> class Color(Enum): ... __slots__ = () ... RED = 0 ... BLUE = 1 ... >>> Color.RED.foo = 'bar' >>> Given that enums are rather special, I didn't exactly *expect* this to work -- but it might be good to raise some kind of error if a user attempts to specify __slots__, instead of having it fail silently. ---------- messages: 408898 nosy: AlexWaygood, ethan.furman priority: normal severity: normal status: open title: Attempting to create an enum with slots silently fails type: behavior versions: Python 3.10, Python 3.11, Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue46132> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
