Well, there are number of ways I guess, but after cleaning up a bit it 
could look like this:

if str.count(substr) > 0:
    do_stuff()

and where the 'str' is the string variable wanted to be checked of
occurances of 'substr', using string-methods. So you don't have to
import string module, but of course, if using old interpreter, you must do
it the old way.
