[Tutor] Equivalent exception of os.path.exists()

This is end-of-chapter3 exercise of the book Core Python Programming.

I'm reading/searching in the book and other materials but is 
unsuccessful. There are at least 50 exceptions listed but I can't find 
anything close.

I commented out my modified script to just what *should* be applicable. 
Can you please point me to the right direction? TIA.
