Martin Panter added the comment: I don’t think you need to define __len__() to get an iterable, only __getitem__().
Also, if I understand your problem, Container would also be susceptible in theory, because membership testing via “in” and “not in” falls back to iteration. If you only define __getitem__(), your class is both iterable and a container, but it is neither an Iterable nor a Container. :) ---------- nosy: +martin.panter _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue25958> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
