Variable out_list consists of list ll repeated however many times. Each time you change ll you're changing it everywhere it appears in out_list. That is, what's being appended to out_list isn't a copy of ll, it's a pointer to ll. You need something like:- out_list.append([ll[0],ll[1]]) And you need to add a return at the end of the function, otherwise it returns None: return out_list -- Michael _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
