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']
>>>
