Do not understand the question.

In the final challenge of Python Regular expressions, the challenge says: "Wow! OK, now, create a class named Player that has those same three attributes, last_name, first_name, and score. I should be able to set them through init." Since we were doing regular expressions, I created a init(self, inTxt) method and used a regular expression to translate the inTxt into the three variables. When I tested in pyCharm it worked. When in ran it in the challenge window; it told me there was an unexpected "score" parameter????

players.py 
import re

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

players = re.match(r'''
      (?P<last_name>^[-\w ]*)
      [, ]{2}
      (?P<first_name>[-\w ]*)
      [: ]{2}
      (?P<score>\d{1,3})$
''', string, re.X | re.M)

class Player():
    last_name = ""
    first_name = ""
    score = ""

    def __init__(self, inTxt):
        xxx = re.match(r'''
                   (?P<last_name>^[-\w ]*)
                   [, ]{2}
                   (?P<first_name>[-\w ]*)
                   [: ]{2}
                   (?P<score>\d{1,3})$
''', inTxt, re.X | re.M)
        self.last_name = xxx.group("last_name")
        self.first_name = xxx.group("first_name")
        self.score = xxx.group("score")

Hi mike! I had the same problem. I think that the solution is easier, because the challenge ask you to create a class that allows someone to add some specific arguments to it. In this sense if I define a general class like this: 

class Player:
    def __init__(self, **kwargs):
        for key, value in kwargs.items():
            setattr(self, key, value)

than you will be able to define its arguments doing for example:

player = Player(**players.groupdict())

Thanks very much. It will be the best answer as soon as I can figure out how to make it so.
