Adding a score method to Game

I am having a little trouble with an OOP code challenge. I can't get the list value to increment by one, but why?

class Game:
  def __init__(self):
    self.current_score = [0, 0]

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

self.current_score[2] isn't going to work since that's out of range. Also self.score() is going to blow up because you didn't provide a player and there's no default. The method doesn't need to return anything either. Once I cleared these things up, your example code passed.

There's an easier way, though. Since player is a number (1 or 2), just decrease it by 1 and then do something like self.current_score[player-1] += 1 (assuming you didn't decrease the player number into a new variable).

Facepalm! The Index was exactly the problem and thank you for the advice with formatting list indexes!
