Bummer

Problem: Add a score method to Game that takes a player argument. The player argument will be either 1 or 2. Increase that player's value in self.current_score by 1. You'll need to adjust the index (i.e. player = 1 means self.current_score[0] needs to increase).

The first 3 lines are given, what's wrong with this code?

game.py
class Game:
    def __init__(self):
        self.current_score = [0, 0]
    def score (self): 
        if self.player == 1:
            self.current_score[0] += 1
            return self.current_score 
        elif self.player == 2:
            self.current_score[1] += 1
            return self.current_score

Hi: the score method has to take player as an argument - see the below code.

class Game:
    def __init__(self):
        self.current_score = [0, 0]
    def score (self, player): 
        if player == 1:
            self.current_score[0] += 1
            return self.current_score 
        elif player == 2:
            self.current_score[1] += 1
            return self.current_score
