Hi there! The problem is in your return string. First, you have some extra spacing that it doesn't want, but also self.score is a tuple that is being used. So we have to access the different items in the tuple. Here's the line I used for the string that's being returned:

return("Player 1: {}; Player 2: {}".format(self.score[0], self.score[1]))

Here we take self.score at the index of 0 which is player 1's score and insert it into the first position, and self.score at the index of 1 and insert it into the second position.

Hope this helps! :sparkles:

Jennifer's solution is correct, but you can also make use of the shorthand for unpacking the tuple:

    return("Player 1: {}; Player 2: {}".format(*self.score))

Also, you don't need pass anymore once you add some code to your class.

There are several problems with your code.

The main problem is probably that you need to reference Game's score variable, which you do with a period instead of a comma.

self.score

Also, since you have Player 1 and Player 2, you will need two variables in format. example:

'Player 1: {}, Player 2: {}'.format(self.score1, self.score2)

I'm assuming score1 and score2 are integers representing Player 1 and Player 2 respectively. If your score variable is a collection, you can just use indexes, such as:

 'Player 1: {}, Player 2: {}'.format(self.score[1], self.score[2])

In the code you have showing, you don't need pass and you don't need to wrap the returned string with parenthesis. Although they are not impacting how the code compiles and runs, they don't improve human readability either.
