im failing to get past this

        if sides < 2:
            raise ValueError("Can't have fewer than two sides")
        self.sides = sides
        self.value = random.randint(1, sides)

    def __int__(self):

Hi Malvin, your code looks great! All you need to do is move everything from from dice import D20 onward into hands.py. So dice.py should contain:

#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)

and hands.py should contain:

#hands.py
from dice import D20

class Hand(list):
    def __init__(self, new_hand):
        super().__init__()
        self.extend(new_hand)

    @classmethod
    def roll(cls, size, die_class=D20):
        new_hand = []
        for _ in range(size):
            new_hand.append(die_class())
        return cls(new_hand)

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

That, said, my brain is sooooo slow. Can you please help me with this challenge?

ef first_function(arg1): return 'arg1 is {}'.format(arg1)

def second_function(arg1): return 'arg1 is {}'.format(arg1)

class MyClass: args = [1, 2, 3] def class_func(self): return self.args

It's the second challenge from Writing Better Python. Thanks!
