Adding a decorator to the Hands class

Upon calling Hand.roll(n), n number of D20 die should be in an instance of Hand returned by the class method roll(n). I have a feeling that my issue is either in how I am instantiating the list passed to cls or how I am importing/instantiating D20 die. D20 is a subclass of Die that is stored in dice.py

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):
        super().__init__(sides)
hands.py
import D20 from dice
class Hand(list):
    @classmethod
    def roll(cls, num):
        die = []
        for _ in range(num):
            die.append(D20())
        return cls(die)

    @property
    def total(self):
        return sum(self)

The "from" should come first in the import statement:

from dice import D20

Otherwise, good job! :+1:

Thanks! I also had to change the Die.D20() to just D20(), but that issue arose from tinkering around with the code to make it work.
