Hi Barry, Have a look at enumerate: >>> list(enumerate('abcdefghijk')) [(0, 'a'), (1, 'b'), (2, 'c'), (3, 'd'), (4, 'e'), (5, 'f'), (6, 'g'), (7, 'h'), (8, 'i'), (9, 'j'), (10, 'k')] You need to work on each tuple in the iterable, but the function takes you halfway. Hope it helps. Victor _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
