Getting a message that a class method doesnt exist

Question

Why is it that i get an error message when i check this? It says that class "Hand" does not have a roll method although it does. When i test the code on my computer it works as it should.

dice.py

import random

class Hand:
    def __init__(self, rolls):
        self.dice_list = []
        for i in range(rolls):
            self.dice_list.append(D20())

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

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




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

The challenge is expecting the Hand class to be implemented in the hands.py file. It does not test the one you put into the dice.py file, even though that works on your computer.
