Didn't get the right content in the groups. Last name was "Perotto, ", first name was "Pier Giorgio".

It looks to me like I got the correct result. What am I not seeing?

names.py 
import re

string = 'Perotto, Pier Giorgio'

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

Jackson, yours and mine look the same to me. Don't I have the \s outside [], for last name?

import re

string = 'Perotto, Pier Giorgio'

names = re.match(r"""
    ^(?P<last>[\w]*,\s)     #<-- in here '',\s" should be out of the bracket
    (?P<first>[\w\s]*)$
""", string, re.X|re.M)

I didn't give you the answer on my last comment, I just told you what you should do. Here is my answer.

import re

string = 'Perotto, Pier Giorgio'

names = re.match(r"""
    ^(?P<last>[\w]*),\s     #<-- in here ",\s" should be out of ()
    (?P<first>[\w\s]*)$
""", string, re.X|re.M)
