The formatting was lost, but it seems you're trying to use two for loops to do something that's easier with a single while loop, and even easier if you take a random.sample() of a set(): http://docs.python.org/release/2.6.7/library/random.html#random.sample >>> import random >>> data = [3,1,4,5,9,3,1,4,5,9] >>> random.sample(set(data), 5) [9, 3, 5, 4, 1] _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
