len(lines[3]) ?? You can do this: [Hope I am not doing your homework!] >>> [(x[-2:] if len(x) > 2 else x) for x in lines] ['12', '42', '49', '56', '25', '36', '49', '64', '81', '00'] >>> For that matter even this works But I am not sure whats happening or that I like it >>> [x[-2:] for x in lines] ['12', '42', '49', '56', '25', '36', '49', '64', '81', '00'] >>> -- https://mail.python.org/mailman/listinfo/python-list
