I am not understand the error ... why is 'length' an error
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)
from dice import Die, D20
class Hand(list):

if not die_class:
raise ValueError("You must provide a die class")
super().__init__()
for _ in range(size):

self.sort
