I have a hunch that you may be looking for slicing: >>> a = [0,1,2,3,4,5,6,7,8,9,10] >>> b = [10,20,30,40,50,60,70,80,90,100,110] >>> a[6:] [6, 7, 8, 9, 10] >>> b[3:] [40, 50, 60, 70, 80, 90, 100, 110] If I'm right you should really work through a tutorial. _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
