New submission from Roy Wellington: Inheriting from collections.MutableSet mixes in several methods, however, it does not mix in a .update method. This can cause a variety of confusion if you expect a MutableSet to act like a set. Moreover, MutableMapping does provide a .update method, which makes me think this is a bug.
I've attached a file that creates a bare-bones MutableSet, and shows the difference. Is this a bug, or is there some reason that MutableSet doesn't provide an update method? ---------- components: Library (Lib) files: ms.py messages: 224105 nosy: roy.wellington priority: normal severity: normal status: open title: collections.MutableSet does not provide update method versions: Python 3.3, Python 3.4 Added file: http://bugs.python.org/file36125/ms.py _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue22089> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
