I can't continue. it says that the Task 1 is no longer passing!!

TASK 1 passes: from game import Game class GameScore(Game): pass

TASK 2 doesn't pass but I really don't know what to do here even if I erase the world 'pass" from de code from game import Game class GameScore(Game): pass def str(self): returns "Player 1:{}; Player 2:{}".format(self.score, self.score)

game_str.py 
from game import Game
class GameScore(Game):
  pass
  def __str__(self):
    returns "Player 1:{}; Player 2:{}".format(self.score, self.score)

Since you don't need a placeholder anymore, you can get rid of pass. You also want to change returns to return.

The instance variable self.score is a tuple, so if you want to use it without selecting the indexes you will have to unpack it:

def __str__(self):
    # Unpack the scores in to two positional arguments.
    return "Player 1: {}; Player 2: {}".format(*self.score)

Thank Dan, You are the king!! I don't understand a lot about unpacking, however I think I will learn it step by step... I hope I understood your suggestion and it worked but I need practice with this. Thank you again Mila

Unpacking a tuple basically turns it into some number of positional arguments. For example:

# If we have score defined like this
score = (5, 10)

# Then these are all functionally equivalent
print( "Player 1: {}; Player 2: {}".format(*score) )
print( "Player 1: {}; Player 2: {}".format(score[0], score[1]) )
print( "Player 1: {}; Player 2: {}".format(5, 10) )

The last line is what you can imagine score looks like after unpacking.
