Why is it wrong?

After submittion I get back a response saying the roll method is not there. It is there so why is this happening?

dice.py 
import random


class Die:
    def __init__(self, sides=2):
        if sides < 2:
            raise ValueError("Can't have fewer than two sides")
        self.sides = sides
        self.value = random.randint(1, sides)

    def __int__(self):
        return self.value

    def __add__(self, other):
        return int(self) + other

    def __radd__(self, other):
        return self + other

    def __iadd__(self,value):
        for i in self:
            self.value += i
        return (self.value)

class D20(Die):
    def __init__(self, value = 0):
        super().__init__(sides = 20)


class Hand(list):
    def __init__(self, size = 0,die_class=None):

        self.die_class = die_class

        if not die_class:
            raise ValueError("You must provide a die class")

        super().__init__()

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

    @property
    def total(self):
        return sum(self)

    @classmethod
    def roll(cls, size,die_class=D20):
        return cls(size,die_class)
hands.py 
class Hand(list):
    @property
    def total(self):
        return sum(self)
