8,254 PointsHow is the class method supposed to look in this exercise?
It is the class method I don't know how to write.
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__()
        self.sides = 20
import D20 from dice.py
class Hand(list):
    #def __init__(self):
    #super().__init__()    
    @property
    def total(self):
        return sum(self)
    @classmethod
    def roll(cls, num_dices):
        hand = cls(num_dices)
        for _ in range(num_dices):
            d20 = D20()
            hand.append(d20)
        return hand

Treehouse TeacherYou need to remove num_dices from this line hand = cls(num_dices) to make it hand = cls() instead. You are appending the dice to this hand inside of your for loop. Hand should just be the empty list to start.
