Bummer: Can't get the length of a `Hand` When I debug in work space I can get the length.

You can see my code attached. To debug I have copied these 2 files into the workspace and enter the following commands in the python environment: from hands import Hand h = Hand() h.roll(2) len(h) #this returns '2' int(h[0]) #this returns the first die value int(h[1]) #this returns the 2nd die value

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=sides)
hands.py
from dice import D20

class Hand(list):

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

    def roll(self, die_to_roll):
        for _ in range(die_to_roll):
            self.append(D20())

The instructions say "I want to get back an instance of Hand ...", but the current "roll" method does not return anyting.

Also, they say "I'm going to use code similar to Hand.roll(2)" and since they will be calling the method directly on "Hand" itself, this should probably be implemented as a class method.
