Can someone help me out with "players.py"? I'm not sure what more they're asking me for...

PROMPT: "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."

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

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

class Player:
    def __init__():
        last_name = []
        first_name = []
        score = []
        for match in players.finditer(string):
            last_name.append('{}'.format(match.group('last_name')))
            first_name.append('{}'.format(match.group('first_name')))
            score.append('{}'.format(match.group('score')))

They are asking for a class named player, which you have created.

Now create the three attributes like so:

class Player:
          last_name = ""
          first_name = ""
          score = 0

Now create the method that allows one to set the attributes like so:

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

This is taught in the Python Object Oriented programming Track. Please refer to it for more information.

Hope that helps.

Kind regards,

Fahad

Thank you very much! I'll return to that lesson. I forgot the setattr() method, and I'm still a little shaky on the key word argument unpacking.

Best,

Dan

Hi Daniel,

Go through the recently updated collections track and also the object oriented track. You will find it in much detail there.

Kind regards,
