Martijn Pieters added the comment: I should have added the mixin methods for the Sequence implementation; the more complete demonstration is:
>>> from collections.abc import Sequence, Container, Sized >>> class MySequence(object): ... def __contains__(self, item): pass ... def __len__(self): pass ... def __iter__(self): pass ... def __getitem__(self, index): pass ... def __len__(self): pass ... def __reversed__(self): pass ... def index(self, item): pass ... def count(self, item): pass ... >>> issubclass(MySequence, Container) True >>> issubclass(MySequence, Sized) True >>> issubclass(MySequence, Sequence) False ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue23864> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
