The reference says: The truth of x==y does not imply that x!=y is false. Accordingly, when defining __eq__(), one should also define __ne__() so that the operators will behave as expected.
(http://docs.python.org/3/reference/datamodel.html#object.__eq__) But I saw different behavior on 3.3: https://gist.github.com/4231096 Could anyone teach me what happen about my code? -- http://mail.python.org/mailman/listinfo/python-list
