So I looked at the other questions for this one but I seem to be the only person getting a 'Hand' doesn't have a 'roll' method error. I see the method right there is this a bug?

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

class D20(Die):
    def __init__(self):
        super().__init__(sides=20)
hands.py
from dice import D20

class Hand(list):
    def __init__(self, size=0, die_class=None, *args, **kwargs):
        super().init()
        for _ in range(size):
            self.append(die_class())


    def __len__(self):
        return super().__len__()

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

    @classmethod
    def roll(cls, size):
        return cls(size, D20)

The message might be misleading.

But when you call the base's "__init__" method, you spelled it "init" (without the "dunders").

Also, you shouldn't need to override the "__len__" method just to call the base's. Access to the base methods should be automatic.

oh thank you very much I could have sworn I double checked it all.
