Python Object-Oriented Python Dice Roller RPG Roller

Bummer! I don't know why this won't work in Workspaces.

Attached is my code. I made roll into a classmethod. When I run the code in Pycharm I can get the total of two D20's by calling print(Hand.roll(2).total). but it doesn't work in Workspaces.

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 __repr__(self):
        return str(self.value)

class D20(Die):
    def __init__(self):
from dice import D20

class Hand(list):
    def __init__(self, sides=0, die_class=None, *args, **kwargs):
        for _ in range(sides):

    def roll(cls, size):
        return cls(sides=size, die_class=D20) 

    def total(self):
        return sum(self)

I tried copying the code above and pasting it directly into the challenge, and it passed.

Give it another try, perhaps after restarting your browser.

Ahh! That's so Frustrating! HAHA! Thanks Steven. I appreciate the Assist.
