New submission from Raymond Hettinger: The dictviews_or() function in Objects/dictobject.c is converting the keys to a set and calling the set.update() method with the given argument. The set.update() method doesn't return NotImplemented because it has no reflected operation.
It looks like dictviews_or() should instead call set.__or__() to allow it a chance to return NotImplemented. The other dictview set operations are similarly afflicted. ---------- priority: normal -> low versions: +Python 2.7, Python 3.5, Python 3.6 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue24413> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
