Regular Expressions in Python Players and Class Definitions Challenge...

I'm not sure what I'm doing wrong. I've got the first part of the challenge done, but I'm having trouble getting the class right.

players.py 
import re

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

line = re.compile(r'^(?P<last_name>[-\w ]+),\s(?P<first_name>[-\w ]+)\:\s(?P<score>[0-9]+)$', re.X|re.M)
players = line.match(string)

class Player:
  line = re.compile(r'^(?P<last_name>[-\w ]+),\s(?P<first_name>[-\w ]+)\:\s(?P<score>[0-9]+)$', re.X|re.M)
  def __init__(self, inputString):
    self.last_name = ''
    self.first_name = ''
    self.score = ''
    self.players = line.match(inputString)

player = Player(string)

Robert, congrats on the first part. Here's a suggestion for the second:

class Player:
  def __init__(self, last_name, first_name, score):
    self.last_name = last_name
    self.first_name = first_name
    self.score = score

There's no need to repeat line in the class, and the init needs to have 4 parameters, rather than 2. Further, the purpose of the init is to provide values for the variables, so each needs to be set to the appropriate value being passed in.
