you didn't get enough groups back

import re

string = 'Perotto, Pier Giorgio' names = re.match(r''' [-\w ]+, #first name [-\w ]+ #last name ''',string, re.X|re.M)

names.py 
import re

string = 'Perotto, Pier Giorgio'
names = re.match(r'''
                 [-\w ]+, #first name
                 [-\w ]+ #last name
                 ''',string, re.X|re.M)

You'll need to add parentheses to identify the groups.

You may also need to specify the space that follows the comma with the "\s" code.
