You have a good idea, but a few implementation issues:

  • the method won't need an argument (the instance "self" is a hand)
  • in doubles, the individual dice will equal each other (not their sum)
  • there are only two dice in the hand, so you only need one comparison (no loop)

Good work on getting task 1 done! For task 2, the challenge is asking you to create a property that checks if both dice in the hand have equal value.

I am going to leave the coding up to you since this can be done in multiple correct ways. Below is a template for your property.

Note:

Since "self" is a LIST... you can check self[0]==self[1] (if True, doubles property should return True else return a False)

    @property
    def doubles(self):
        # your code goes here...
        # return True or False (depending on the outcome of self[0] compared to self[1]
