Comment: This rule applies to special methods like __getitem__ and __setitem__. 'lis.append(item)' is equivalent to lis.__setitem__(len(lis):len(lis), item), so it should not be so surprising that it has the same return.
It's not true for all special methods. __iadd__ and __imul__ return the list itself. That's a minor nitpick though. +1 on adding "and return None" to the docstrings of methods that often trip people up. Not everyone will read them, but some people will. ---------- nosy: +stutzbach _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue12192> _______________________________________
