The 'for in' construct loops over the items of a sequence, and the range function creates a sequence (list) of integers. It is described here: http://docs.python.org/lib/built-in-funcs.html so your code is equivalent to: index = 0 while index < len(myList) : myList[index] += 1 index += 1 -- Cédric Lucantis _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
