What you wrote will work, but catching a ValueError (except ValueError:
...) is a better solution. Especially in dynamically typed languages
like Python, it's a good idea to catch the most restrictive error you
think you need, and then expand the net if it's required. This way only
what needs to get caught gets caught, and the rest gets passed up the
appropriate caller if necessary.
Granted, this is a special case since what you're trying to do is so
simple, but it's a good practice to follow in the future.
