Python String to Int Or None

Question

Learning Python and a little bit stuck.

I\'m trying to set a variable to equal int(stringToInt) or if the string is empty set to None.

Answer 1

Here are some options:

Catch the exception and handle it:

try:
    variable = int(stringToInt)
except ValueError, e:
    variable = None

It's not really that exceptional, account for it:

   variable = None
   if not stringToInt.isdigit():
       variable = int(stringtoInt)
