When the number of groups is significant, or when modifying the group, managing the indices to the group can prove to be a challenge. If analysis of the groups is needed, we can also name the groups.>>> reobj = re.compile('(?P<prefix>a)(?P<body>b+)(?P<suffix>a)')

>>> m = reobj.search('hello abba world')

>>> m.group('prefix')

'a'

>>> m.group('body')

'bb'

>>> m.group('suffix')

'a'

Since regular expressions can get dense, there is a way to make them a bit easier to read: the verbose mode.>>> reobj = re.compile(r"""

... (?P<prefix>a) # The beginning -- always an a

... (?P<body>b+) # The middle -- any numbers of b, for emphasis

... (?P<suffix>a) # An a at the end to properly anchor

... """, re.VERBOSE)

>>> m = reobj.search("hello abba world")

>>> m.groups()

('a', 'bb', 'a')

>>> m.group('prefix'), m.group('body'), m.group('suffix')

('a', 'bb', 'a')
