[Tutor] What is wrong with my code?

[apometron]

Sorry to continue discussing my thread on this list, I already subbed on 
the Tutor list
but I need to reply and if possible, some ideas of why it dont works. 
Now it is another
thing, entirely. Rename1.py and Rename2.py works, but why Rename3.py 
dont works?
