Can't get the length of a hand

I don't know what it means. I've tried it in an external IDE and it seems to work.

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

    def __repr__(self):
        return str(self.value)

class D20(Die):
    def __init__(self):
from dice import D20

class Hand(list):
    def __init__(self, *args, **kwargs):

    def roll(self, size, die_class=D20):
        for _ in range(size):
        return self

    def total(self):
        return sum(self)
