I dont understand this, it is so confusing.

In the file import the D20 class from Create a classmethod named roll. It should take take the number of dice as an argument. Inside the roll classmethod create an empty list. Append a D20 to your list equal to the number of dice given as an argument to the roll classmethod. Then return the list of D20s. For example, if Hand.roll(2) is called, it would return a list with two D20s inside.
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):

from dice import D20

class Hand(list):
    def __init__(self, size=0, die_class=D20, *args, **kwargs):
        for _ in range(size):

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

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

Here's some hints:

  • keep the implementation of "hand" in the "" file (tab)
  • all work can be done in the new "roll" method, you won't need to override "__init__"
  • you can use "cls" to create a new instance and then add items to it
