I don't know what to do next

What is the next step here.This is for challenge task part 1

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

Hi Aizah

The task says you need to create a new class in dice.py named D20 that extends Die. It should automatically have 20 sides and will not need any arguments to create.

I think it's easier for me to walk you through the code I used when I learned this:

class D20(Die):     # create a new class that extends Die
    def __init__(self):     # the __init__() method takes in the information required to make a Die instance
        super().__init__(sides = 20)    # special function that allows you to call a method from the parent class

'Die' is the parent class and 'D20' is the child class inheriting from 'Die'. As the challenge states, the new class should automatically have 20 sides so this is why we write 'sides = 20' and that's why the class is named D20.

I hope this makes sense!
