Claudiu Saftoiu added the comment: Ahh, I see. In that case, if the object passed-in has a length, use that. If not, then raise TypeError. e.g. proposed behavior:
>>> len(itertool.combinations(range(10), 2)) 45 >>> len(itertool.combinations(iter(range(10)), 2)) ... TypeError: itertools.combinations underlying object has no len() ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27678> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
