I don't understand what output is expected. I did define groups and when running it in my own editor it returns the data

What is th expected output?

players.py 
import re

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


pattern = r'''
(?P<last_name>[\w]+),?\s?
(?P<first_name>\s[\w]+):\s
(?P<score>[\d]+)
'''

players = re.match(pattern, string, re.X|re.M )

It's easy to miss, but look very carefully at the error message:
:point_right: Bummer: Didn't get the expected match. Got "{'last_name': 'Love', 'first_name': ' Kenneth', 'score': '20'}".

You can see that ' Kenneth' has a space inside the quotes, right at the front. The regex should handle a space between the names, but not capture one as part of a name.

Once that's fixed, you'll also need a few tweaks to mark the line boundaries and to accommodate special cases such as the multiple-word names in the last example.
