Python doesn't have regular expressions as a language feature. It's
just a module in the standard library.

import re
if re.search(pattern, string) :
   Stuff


However, regular expressions aren't used as much in Python as they are
in Perl. Regular expressions are overkill for a lot of applications.
If you're just checking to see if a string contains some text, use "if
substring in string". If you're checking to see if some text is at the
start of the string, do string.startswith(substring).
