Michael K. Edwards <m.k.edwa...@gmail.com> added the comment: The implementation you are looking for is in object_richcompare, in http://svn.python.org/projects/python/branches/py3k/Objects/typeobject.c . It would be most accurate to say something like:
The "object" base class, from which all user-defined classes inherit, provides a single "rich comparison" method to which all of the comparison operators (__eq__, __ne__, __lt__, __le__, __ge__, __gt__) map. This method returns a non-trivial value (i. e., something other than NotImplemented) in only two cases: * When called as __eq__, if the two objects are identical, this method returns True. (If they are not identical, it returns NotImplemented so that the other object's implementation of __eq__ gets a chance to return True.) * When called as __ne__, it calls the equivalent of "self == other"; if this returns a non-trivial value X, then it returns !X (which is always either True or False). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue4395> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
