best way to do a series of regexp checks with groups

[wittempj at hotmail.com]

what about something like this?
>>> import re
>>> m = re.match(r"""(?P<operator>add|mult) (?P<int_1>\d+)
(?P<int_2>\d+)""", 'add 3 5')
>>> from operator import add, mul
>>> op = {'add': add, 'mult: mul}
>>> op[m.groupdict()['operator']](int(m.groupdict()['int_1']),
int(m.groupdict()['int_2']))
