I am getting the wrong length of Hand, I am totally lost as to why

Need some help walking through all of this.

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):
        super().__init__(sides = 20)
hands.py
from dice import D20

class Hand(list):
    @property
    def total(self):
        return sum(self)


    @classmethod
    def roll(cls, num_dice):
        new_hand = cls()

        for num in range(0, num_dice):
            new_hand.append(D20())
            return new_hand

Here is the question: In the hands.py file import the D20 class from dice.py. Create a classmethod named roll. Since it is a classmethod, it will take cls as an argument. It will also take the number of dice as an argument. Inside the roll classmethod create a new instance of the Hand class and assign it to a variable. Append a D20 to your Hand equal to the number of dice given as an argument to the roll classmethod. Then return the Hand of D20s. For example, if Hand.roll(2) is called, it would return a list with two D20s inside.

I figured it out....my return statement was indented too far.
