And, finally, if I have doubles, I want to reroll the hand.

So I've tried to follow the instructions in the questions asked by others, but no dice (pun intended). Can someone please explain why the code I've used is not working?

Thanks!

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, *args, **kwargs): 
        super().__init__(size=2, die_class=D6, *args, *kwargs)

    @classmethod
    def reroll(cls):
        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)
        }

    @property
    def doubles(self):
        for num in self._sets.values():
            if num > 1:
                return True
        return False

In your doubles method, you are not telling the class to run the reroll method, you are simply returning True or False.
