And, finally, if I have doubles, I want to reroll the hand. Add a classmethod to CapitalismHand named reroll that return

I need so much help.

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

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



class CapitalismHand(Hand):
    def __init__(self, *args, **kwargs):
        super().__init__(size=2, die_class=D6, *args, **kwargs)
    @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 last step is simply a matter of returning a new instance, and since a classmethod gets its own class as the first argument (typically named "cls"), you can just use it to "return cls()".

Also, while your step 2 code was fine, you could make it more compact by simply returning the result of the comparison directly:

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

It also could have been added to "CapitalismHand" instead of "Hand".
