Don't know what to do?

What does "wasn't able to create correct instances" means?

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.M)
class Player:
    last_name = "last_name"
    first_name = "first_name"
    score = "score"
    string = '''Love, Kenneth: 20
Chalkley, Andrew: 25
McFarland, Dave: 10
Kesten, Joy: 22
Stewart Pinchback, Pinckney Benton: 18'''
    def __init__(self,last_name,score,first_name):
        self.players = re.search(r"(?P<{}>[\w ]+),\s(?P<{}>[\w ]+):\s(?P<{}>[\d]+)".format(self.last_name, self.first_name, self.score), self.string, re.M)

:point_right: It looks like you're getting a bit too fancy there. You don't need to build the string or the re.search into the class. Just simply define the three properties mentioned and set them from the arguments passed to __init__.

Also, remember that score holds a number, not a string.

I'll bet you can get it now without an explicit spoiler.

You can do it with def init(self,**kwargs): for key,value in kwargs.items(): setarrt(self,key,value)

Kenneth covered it in the previous courses
