Any part of a regular expression in parentheses is treated as a group.

 >>> import re
 >>> re.findall(r'(a)b(c)', 'abcabc')
[('a', 'c'), ('a', 'c')]
 >>>m=re.search(r'(a)b(c)', 'abcabc')
 >>> m.groups()
('a', 'c')

You can name the groups:
 >>> m=re.search(r'(?P<one>a)b(?P<two>c)', 'abcabc')
 >>> m.groupdict()
{'two': 'c', 'one': 'a'}
