Antoine Pitrou added the comment: I don't think "in" is the right operator for this. You can draw an analogy with sets:
>>> a = {1,2} >>> b = {1,2,3} >>> a <= b True >>> a in b False In mathematical terms, there is a difference between inclusion (being a subset of) and containment (being an element of). ---------- nosy: +pitrou _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue20825> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
