New submission from Gregory Salvan: It's a small refactoring.
Lurking at collections.abc I found a lot of: >>> any(attr in B.__dict__ for B in C.__mro__) also repeated in typing.py of mypy: https://github.com/JukkaL/mypy/blob/master/lib-typing/3.2/typing.py#L117 It seems to be a common operation to check or get an attribute from mro in abc, so I thought it could help to have dedicated functions to enhance readability. (see patch e.g. Hash.__subclasshook__ takes 1 line intead of 7...) ---------- components: Library (Lib) files: mroattr.patch keywords: patch messages: 225842 nosy: Gregory.Salvan priority: normal severity: normal status: open title: mrohasattr and mrogetattr type: enhancement versions: Python 3.5 Added file: http://bugs.python.org/file36458/mroattr.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue22268> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
