Grouping

• Groups are defined using parentheses

  • E.g.
    >>> regex = re.compile('(ab*)(c+)(def)')
    >>> match = regex.match("abbbdefhhggg")
    >>> print match
    None
    >>> match = regex.match("abbbcdefhhggg")
    >>> print match
    <_sre.SRE_Match object at 0x00A35A10>
    >>> match.groups()
    ('abbb', 'c', 'def')
