Alright! Now I need you to add a new property called doubles. It should return True if both of the dice have the same va

Adding new property "Doubles" Wanting to return True if doubles are rolled. Am I getting close or have I veered off the track again?

hands.py 
from dice import D6


class Hand(list):
    def __init__(self, size=0, die_class=None, *args, **kwargs):
        if not die_class:
            raise ValueError("You must provide a die class")
        super().__init__()

        for _ in range(size):
            self.append(die_class())
        self.sort()

    def _by_value(self, value):
        dice = []
        for die in self:
            if die == value:
                dice.append(die)
        return dice


class CapitalismHand(Hand):
    def __init__(self):
        super().__init__(size = 2, die_class = D6)

    @property          # I think my mistake is in here, just not sure what I am doing wrong
     def doubles(self):
        for num in self._sets.values():
            if num > 1:
        return  True
        return  False  # if the loop does not return True allows method to exit gracefully




    @property
    def ones(self):
        return self._by_value(1)

It looks like you just have some indentation issues. The "def" should line up with "@property" above it, and the final "return" needs to line up with the "def".

You already set self as two D6, so you only have to compare yourself twice, [0] and [1]. Such as:

def doubles(self):
        return self[0] == self[1]

If they match it will equal True and return it. If they do not match it will equal False and return that.
