Regex right results vs expected results

Didn't get the right results. Got [('Love', 'Kenneth', '20'), ('Chalkley', 'Andrew', '25'), ('McFarland', 'Dave', '10'), ('Kesten', 'Joy', '22')].

Last line is bit weird. It means that both players have the same score or only last player has score?

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]?), (?P<first_name>[\w]+[\s]?[\w]?): (?P<score>[\d]+$)',string,re.MULTILINE)
#Didn't get the right results. Got [('Love', 'Kenneth', '20'), ('Chalkley', 'Andrew', '25'), ('McFarland', 'Dave', '10'), ('Kesten', 'Joy', '22')].

The last line is still one name despite its looks: P. B. S. Pinchback

All you need to change to capture it is to capture zero or more characters after the optional space instead of having a single optional character captured.

You can also drop the brackets around the character and white space sets if you'd like. You only need the brackets if you're dealing with multiple sets.
