New submission from Brett Cannon <br...@python.org>:
https://docs.python.org/3/reference/datamodel.html#object.__ror__ has a note saying: "If the right operand's type is a subclass of the left operand's type and that subclass provides the reflected method for the operation, this method will be called before the left operand's non-reflected method." The slightly unclear part (at least to me) is the "provides the reflected method." What this actually means according to https://bugs.python.org/issue30140 is that the subclass **implements** the `__r*__` method, not just that the method is reachable on the subclass via getattr(). That wasn't clear to me when I initially read this. ---------- assignee: docs@python components: Documentation messages: 375621 nosy: brett.cannon, docs@python priority: normal severity: normal stage: needs patch status: open title: Clarify documentation for binary arithmetic operation subclass __r*__ precedence versions: Python 3.10, Python 3.8, Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue41584> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
