New submission from Chris Cogdon <chris@cogdon.org>: The documentation for dataclasses.dataclass includes this text: "If any of the added methods already exist on the class, a TypeError will be raised." However, the documentation for various options has ONE case of TypeError, some cases of ValueError and other cases of "does nothing". I'll attempt a fix and create a PR for this. ---------- assignee: docs@python components: Documentation messages: 320444 nosy: chriscog, docs@python priority: normal severity: normal status: open title: Inconsistency in exceptions for dataclasses.dataclass documentation versions: Python 3.7 _______________________________________ Python tracker <report@bugs.python.org> <https://bugs.python.org/issue33961> _______________________________________
