Let exception fire or return None

I have a function to fetch a message from a file:
def get_indexed_message(message_filename, index):
Get index message from a file, where 0 gets the first message
return open(expanduser(message_filename), 'r').readlines()[index].rstrip()
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.
