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

Use the fact that it generates an exception:

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

This has the pleasant side-effect of binding variable to None for other common errors: stringToInt='ZZTop', for example.
