Jelle Zijlstra added the comment: The docstrings (at least in 3.6) say subclasses must override __new__ *or* __init__. However, I think this is wrong too. The following is a correct (if not very useful) implementation of Sequence:
>>> import collections.abc >>> class MySequence(collections.abc.Sequence): ... def __getitem__(self, key): ... raise IndexError(key) ... def __len__(self): ... return 0 ... Other abc docstrings also don't claim that __init__ or __new__ must be implemented. The attached patch fixes the docstrings. ---------- keywords: +patch nosy: +Jelle Zijlstra Added file: http://bugs.python.org/file43245/issue27215.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27215> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
