Can someone help me with why this regex doesn't match multiline

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_name>\w+(\s\w+)?),\s(?P<first_name>\w+(\s\w+)?):\s(?P<score>\d+)',string,re.M)

players = re.match(r''' ^(?P<last_name>\w+(\s\w+)?),\s (?P<first_name>\w+(\s\w+)?):\s (?P<score>\d+)$ ''',string,re.MULTILINE|re.X)

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_name>\w+(\s\w+)?),\s(?P<first_name>\w+(\s\w+)?):\s(?P<score>\d+)',string,re.M)
players = re.match(r'''
^(?P<last_name>\w+(\s\w+)?),\s
(?P<first_name>\w+(\s\w+)?):\s
(?P<score>\d+)$
''',string,re.MULTILINE|re.X)

Another example of my validation being a bit too picky. Since you're using extra groups for the optional extra words in the names, my comparison was wrong and it triggered the fail state. I've fixed it so you should be able to pass now.

In the future, though, it's generally better to use sets to define options instead of bringing it more groups. Groups cause the regex engine to do more work and can make it harder to get the index number for a particular match.
