And rarely used. Probably even less than the (also missing) < in, | in, you-name-it operators... > So, precisely, you mean that if hash(a) != hash(b), a and b are > considered distinct, and else [ie. if hash(a) == hash(b)], a and b are > the same if and only if a == b ? Correct for set, dict. For lists etc. the hash doesn't matter: >>> class A(object): ... def __hash__(self): ... return nexthash() ... def __eq__(self, other): ... return True ... >>> from itertools import count >>> nexthash = count().next >>> A() in [A() for _ in range(3)] True >>> d = dict.fromkeys([A() for a in range(3)]) >>> d.keys()[0] in d False Peter -- http://mail.python.org/mailman/listinfo/python-list
