"Small" ints are cached, so there may be only one instance of the int with value 0. However, that's an implementation detail, which may change from version to version, and is not generally true: py> x = 0; y = 3-3 py> x == y True py> x is y True py> x = 357900001; y = 3579*100000+1 py> x == y True py> x is y False So in general, there can be many instances of int with the same value. That's not what immutable means. -- Steven. -- http://mail.python.org/mailman/listinfo/python-list
