Specifies the step value, as in: foo[start:stop:step] When not specified it, defaults to 1. So foo[::-1] gives the entire sequence backwards. Analogously, foo[::2] gives every other item in the sequence, forwards. Cheers, Chris -- http://blog.rebertia.com -- http://mail.python.org/mailman/listinfo/python-list
