I believe I tried both and they are failing. I'm lost.
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]+),\s
(?P<first_name>[\w\s]+):\s
(?P<score>\d{1,9})$
''', string, re.X|re.M)
class Player:
def __init__(self):
d = players.groupdict()
self.last_name = d['last_name']
self.first_name = d['first_name']
self.score = d['score']

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

13,362 PointsThanks. That works. However, I'm still stunned that this second code challenge has no relevance with regex using words like "the same last_name..." that seemingly suggest to connect with the first code challenge on a regex pattern. Why should there be two codes in a single file of "players.py"? I think if we make the challenges more educational, we had better provide an API to show how to use the regex in an object creation.

Treehouse Guest TeacherYou are using the regex in object creation. And you're doing it in the right manner. Why would you create a class object directly from a string? That requires a huge amount of coordination between the different pieces of code. Better for the class to expect some attributes and not worry about where they come from.
TJ Takei
13,362 PointsTotally agreed as to a sound design of the Player class. And I'd vote for eliminating the second challenge out of the regex module as it has nothing to do with.

Treehouse Guest TeacherIt has nothing to do with the regular expression engine, no. It does, however, have to do with the course (it's, effectively, what I told you to do as extra credit at the end of the last video) and it ties into how to make further use of the data you harvest from a regular expression. Most of the code you'll write in the real world will not be 100% pure and segregated code.
