It means the class defines a __getitem__ method. Like __call__, the semantics of that method, and the range of acceptable arguments, is out of scope of the ABC. I don't believe that Python has any way to check the semantics of a method call, except to call it and see what it does. -- Steve (the other one) _______________________________________________ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/ILP3AH5VBWHCD4GT5QMYFMZ4SWREVQ6B/ Code of Conduct: http://python.org/psf/codeofconduct/
