Comparing and Combining Dice error

When running the code, I get an error that there was an unexpected keyword argument 'sides'. I don't see what I did wrong. I watched the video maybe a dozen times to see if I typo'd something but I just don't see it.

import random

class Die: def init(self, sides = 2, value = 0): if not sides >= 2: raise ValueError("Must have at least 2 sides") if not isinstance(sides, int): raise ValueError("Sides must be whole number") self.value = value or random.randint(1, sides)

def __init__(self):
    return self.value

def __eq__(self, other):
    return int(self) == other

def __ne__(self, other):
    return not int(self) == other

def __gt__(self, other):
    return int(self) > other

def __lt__(self, other):
    return int(self) < other

def __ge__(self, other):
    return int(self) >= other

def __le__(self, other):
    return int(self) <= other

class D6(Die): def init(self, value = 0): super().init(sides = 6, value = value)

d6 = D6()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/treehouse/workspace/yatzy/dice.py", line 36, in init
super().init(sides = 6, value = value)
TypeError: init() got an unexpected keyword argument 'sides'

It's difficult to read without formatting, but the code for "Die" class includes this method definition:

def __init__(self):
    return self.value

Clearly, this method takes no arguments. But when it is called from "D6":

    super().__init__(sides = 6, value = value)

Two keyword arguments are being passed to it. These will be "unexpected".
