srtring to int question

[Olivier Dagenais]

Since everybody else mentionned exceptions, I will mention two other ideas:
filter out all non-digits (using the built-in filter function) or use "in":

if ( (lowercase + uppercase) in user_string ):
    # invalid string!

Unless I'm too tired to notice something???
