For objects that don't have total ordering, "not equal" != is not the same as "less than or greater than" <>. The two obvious examples are complex numbers, where C1 != C2 can be evaluated, but C1 <> C2 is not defined, and NaNs, where NaN != NaN is always true but NaN <> NaN is undefined. -- Steven. -- http://mail.python.org/mailman/listinfo/python-list
