>>> import re
>>> s= 'yadda widget1 widget2 yadda'
>>> regex = re.compile('yadda (widget1) (widget2) yadda')
>>> for match in regex.search(s).groups(): print match
... 
widget1
widget2

This works here.  Although I would strongly caution you to do:

re_match = regex.search(s)
if re_match != None ......

just in case the regex fails.
