Create a variable names that is an re.match() against string. The pattern should provide two groups, one for a last name

very confused any input helps

names.py 
import re

string = 'Perotto, Pier Giorgio'
names = re.match(r'''
                 (?P<Lastname>[\w,]+)
                 (?P<Firstname>[ \w]+)''', 
                 string, re.X|re.I)

Hi Samuel.

This passes:

import re

string = 'Perotto, Pier Giorgio'
names = re.match(r'([\w]*),\s([\w ]*)',string, re.I)

so does this:

import re

string = 'Perotto, Pier Giorgio'
names = re.match(r'([\w, ]*),\s([\w\s]*)',string, re.I)

and this:

import re

string = 'Perotto, Pier Giorgio'
names = re.match(r'([\w,]*),\s([\w\s]*)',string, re.I)
