what's wrong with my answer?

Couldn't find where's going wrong?

players.py 
import re

string = '''Love, Kenneth: 20
Chalkley, Andrew: 25
McFarland, Dave: 10
Kesten, Joy: 22
Stewart Pinchback, Pinckney Benton: 18'''

players = re.search(r'(?P<last>[\w]+),\s(?P<first>[\w]+):\s(?P<score>[\d]+)', string, re.M)

This is a great start - I'd suggest using the triple quotes & re.X as a way to break apart your groups and help you debug, like this:

players = re.search(r'''
  (?P<last>[\w]+),\s
  (?P<first>[\w]+):\s
  (?P<score>[\d]+)
''', string, re.M|re.X)

Two main things to look at:

first (^) and last ($) indicators to help regex parse the multi-line string

players = re.search(r'''
  ^(?P<last>[\w]+),\s
  (?P<first>[\w]+):\s
  (?P<score>[\d]+)
''', string, re.M|re.X)$

And a way to account for the double first name, double last name of the last player

players = re.search(r'''
  (?P<last>[\w\s]+),\s
  (?P<first>[\w\s]+):\s
  (?P<score>[\d]+)
''', string, re.M|re.X)
