Problem in the above code, unable to pass this challenge! Works perfectly on workspace...

Score method is created on the Game class, and asks the user to enter 1 or 2 and the number is summed to the self.current_score list! But unable to pass the challenge, any help will be appreciated!! Thanks!!

game.py 
class Game:

     def score(self):
        player = int(input("Type 1 or 2! "))
        if player == 1:
            self.current_score[0] = self.current_score[0] + 1
        elif player == 2:
            self.current_score[1] = self.current_score[1] + 2
        else:
            return self.score()

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

Hi Rolando,

Your logic is on the right track but the reason it is not passing the challenge is because you are adding in some extra things that the challenge did not ask for.

First, the challenge does not ask you to accept an input from a user.

Add a score method to Game that takes a player argument. The player argument will be either 1 or 2.

So the score method will need to have an argument named "player" that will be passed in. You will need to account for that in your method definition. By adding a user input you are effectively overriding the "player" value that the code checker is trying to pass in.

Secondly,

Increase that player's value in self.current_score by 1.

The score method is used to increment each player's score by one. The only condition to be tested is which player you need to increment (which you are doing correctly).

But notice your handling of Player 2. You are incrementing Player 2's score by two.

And lastly, the challenge doesn't ask you to handle an else condition that calls itself. In this case, it won't affect whether it passes or not, but going outside the scope of the challenge instructions will usually cause problems.

Hope this helps.
