Well, depending on how you think about Counters, the current behaviour of equality definitely leads to some surprises. For example: >>> Counter(a = 3) + Counter(b = 0) == Counter(a = 3, b = 0) False OTOH, if we're consistent about regarding a count of 0 as 'equivalent' to a missing element, then __nonzero__ / __bool__ probably needs changing, too. >>> c = Counter(a = 0) >>> bool(c) True >>> bool(c + c) False ---------- nosy: +mark.dickinson _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue14182> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
