TypeError: __init__() takes 1 positional argument but 2 were given

I just give class Player one argument ? But somehow get a TypeError. why? And how to fix it. thx

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
(?P<first_name>[\w ]*):\s
(?P<score>[\d]*)$
''',string, re.X|re.M)

class Player:
    last_name = []
    first_name = []
    score = []

    def __init__(self, **kwargs):
        self.last_name = kwargs['last_name']
        self.first_name = kwargs['first_name']
        self.score = kwargs['score']

Player(players.groupdict())

You need to expand the groupdict() into keyword arguments for **kwargs. Change your instantiation of Player to:

Player(**players.groupdict())
