How about

import re
re.match(".*born.*to", "This is a test")
re.match(".*born.*to.*", "This test was born so that it worked too.")

(Try these at the python prompt)

The first call to 're.match()' returns 'None' which will fail an if
test.  The second one returns a match object, which evaluates to TRUE
in an if test.
