I have no idea why this is not working. Can someone tell me whats wrong with my code?
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)
import D20 from dice.py
class Hand(list):
def __init__(self, die_class = None , size = 0, *args, **kwargs):
if not die_class:
raise ValueError("You must provide a die class.")
super().__init__()
for _ in range(size):
self.append(die_class())
@property
def total(self):
return sum(self)
@classmethod
def roll(cls,size):
return cls(die_class = D20, size)

for _ in range(size):
self.append(die_class())
needs to be in your roll method and part of your return. You'll need to add the self.value and self. sides back to the main class method. Then take out the super().init, as its not needed. For the roll method you basically need an empty list, your for loop, and the return of that list. Since its a class method, you don't use self, you use cls. Mine looked like below:
@classmethod
def roll(cls, number_of_dice, die_type = D20):
hand = []
for d in range(number_of_dice):
hand.append(die_type)
return cls(hand)
