Hand roll

Hi there,

I don't understand what to do for this challenge. Have looked up part of the code from another help question. Please advise what needs to be done.

The advanced objects section was really quite difficult.

Thanks, Omer

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):
    def __init__(self, size=2, die_class=D20, *args, **kwargs):
        super().__init__()

    for _ in range(size):
        self.append(D20())

    @classmethod
    def roll(cls, size=2):
        return cls(size)

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

The for loop of Hand needs to be indented to be inside the __init__ method. Otherwise, "size" is not defined and the parsing fails.

Thanks. I indented the for loop and still getting error message "Couldnt import Hand". I think the rest of the code is wrong too. Any ideas?
