Actually, ignore my last post. :)  There's a better way: use '.', which will
match any character, instead of '[^%]': 

>>> str=r"blah blah blah %%%important stuff to be extracted%%%more useless junk"
>>> import re
>>> group=re.search(r"%%%(.+)%%%", str)
>>> group.groups()
('important stuff to be extracted',)
