Names.py

I get this error and i don't understand why: Bummer: Hmm, no .groups() attribute. Did you do a match?

names.py 
import re

string = 'Perotto, Pier Giorgio'

names = re.match(r"""
^(?P<last>[\w]+),\s
 (?P<first>[\w\s]+)$
 """, string, re.I | re.M)

The code doesn't have a group() attribute because it gives None as output, but can anyone help me to understand why this code can't find the first and the last name?

Nevermind guys. I tried the same code in single line without the ^ $ and re.M and the group names (?P<>) and it worked. But if anyone can explain the diffrence to me i would be glad :)
