if you find yourself using range a lot, maybe you should check if you couldn't use custom iterators more often. or use the R helper: >>> R[3:20:6] [3, 9, 15] >>> R[:20] [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19] >>> R[0:20:2] [0, 2, 4, 6, 8, 10, 12, 14, 16, 18] >>> R[1:20:2] [1, 3, 5, 7, 9, 11, 13, 15, 17, 19] where R is defined as: >>> class R: ... def __getitem__(self, slice): ... return range(*slice.indices(slice.stop)) ... >>> R = R() </F> -- http://mail.python.org/mailman/listinfo/python-list
