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.
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__()
class Hand(list):
@property
def total(self):
return sum(self)

", 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.
