I have a function to fetch a message from a file:

What is more the Python way: let the exception fire like this code
when index is to big, or catching it and returning None?
I suppose working zero based is OK.
Fire an exception.
One advantage is that the exception will pinpoint exactly which line of
the function had a problem.
