Having a hard time understanding the question and as a result can't get correct answer.

The question is: 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).

I'm not really understanding what this challenge is wanting me to do.

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

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

Currently you are referencing the correct variable and you are adding 1 to it, however you aren't setting that variable equal to its current value +1, for example:

>>>current_score = 0
>>>current_score +  1
1
>>>current_score
0
>>>current_score += 1
>>>
>>>current_score
1

The latter is essentially saying current_score = current_score + 1 which is updating that variable. The former is doing a calculation but the variable isn't set to it.

Also if there are 2 options, either 1 or 2 there is no need for 3 test sequences. If its not 1 than it must be 2.

Here is the solution and I hope I have helped.

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

Thanks for your help! It all makes sense now and I completed the challenge. :)
