Create a new class in dice.py named D20 that extends Die.

Create a new class in dice.py named D20 that extends Die. It should automatically have 20 sides and shouldn't require any arguments to create. Don't know what's wrong.

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, sides=20, *args, **kwargs):
        super().__init__()
hands.py 
class Hand(list):
    @property
    def total(self):
        return sum(self)

In your override of "__init__", you have established a default value for "sides", but when you call the base (super) implementation, you forgot to pass that argument along to it.
