Capitalism, the Game challenge part 3 help

Challenge: And, finally, if I have doubles, I want to reroll the hand. Add a classmethod to CapitalismHand named reroll that returns a new instance of the class, effectively rerolling the hand.

Could someone point out what is wrong with my 'reroll' classmethod. Am I calling self.doubles correctly?

Thank You

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, size=0, die_class=None, *args, **kwargs):
        super().__init__(size=2, die_class=D6)

    @property
    def doubles(self):
        if self[0] == self[1]:
            return True
        else:
            return False

    @classmethod
    def reroll(cls):
        if self.doubles is True:
            return cls()

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

    @property
    def twos(self):
        return self._by_value(2)

    @property
    def threes(self):
        return self._by_value(3)

    @property
    def fours(self):
        return self._by_value(4)

    @property
    def fives(self):
        return self._by_value(5)

    @property
    def sixes(self):
        return self._by_value(6)

    @property
    def _sets(self):
        return {
            1: len(self.ones),
            2: len(self.twos),
            3: len(self.threes),
            4: len(self.fours),
            5: len(self.fives),
            6: len(self.sixes)
        }

The discussion about the relationship between "reroll" and having doubles wasn't meant to be part of the code. Your "reroll" method should simply return a new hand.

Thanks Steven. This was very unclear from the question. I spent a fair whack of time struggling, as I was incorporating the re-rolling element.
