How to make the doubles property work

I tried a lot of thing but I can't seem to make this work. I don't know how to ask my program to compare the value of the 2 dice to make my fonction doubles

hands.py 
from dice import D6


class Hand(list):
    def __init__(self, size=2, die_class=D6, *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):

    @property 
    def doubles(self):
        if self.[0]==self[1]:
            return true 
        else :
            return false





    @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)
        }

I think you can do without if..else by just returning self[0] == self[1]. I did this inside the parent class and it worked although I see it is supposed to be done in the CapitalismHand class.
