How can I get part of regex match as a variable in python?

Question

In Perl it is possible to do something like this (I hope the syntax is right...):

$string =~ m/lalala(I want this part)lalala/;
$whatIWant = $1;

Answer 1

import re
match = re.match('lalala(I want this part)lalala', 'lalalaI want this partlalala')
print match.group(1)
