I know the solution to my problem is to remove the self from the line
super.().__init__(self, sides=20)
but why?
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__(self, sides=20)
class Hand(list):
@property
def total(self):
return sum(self)
