I'm not sure why my code isn't passing.

I'm referring the hands.py file. Below is the class I wrote. I've run this with the interactive prompt on my computer and it runs fine. Maybe I'm missing or not understanding a requirement? It would be helpful if you actually got the reason for he bummer and not just "Try again".

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 
class Hand(list):
    def __init__(self, size = 2):
        super().__init__()

        for _ in range(size):
            self.append(D20())       


    @classmethod
    def roll(cls, rolls):
        return cls(size=rolls)

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

I can think of two issues you may be having. First, "hands.py" probably needs this:

from dice import D20

Then, the new code shouldn't modify how "Hand" works when not using "roll". But previously, a "Hand" instance created with no arguments would be empty. With this code, it would have 2 D20's in it.

This was right on. I had forgotten to import dice.
