The challenge is: "Create a variable names that is an re.match() against string. The pattern should provide two groups, one for a last name match and one for a first name match. The name parts are separated by a comma and a space." I did what I thought would work, but keep getting 'first' and 'last' backwards. I haven't had a problem with regex until this.
import re
string = 'Perotto, Pier Giorgio'
names = re.match(r'([\w]*)([,\w ]*)',string, re.I)

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

Treehouse Moderator 68,441 PointsActually the asterisk should be a plus sign. The asterisk means zero or more of the character set the + means one or more. I think you need the one or more variety.
