2,062 PointsTypeError: __init__() got an unexpected keyword argument 'sides'
I'm getting an typerror and not sure how to fix it. This is the code...
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 a 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 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 or int(self) == other
def le(self, other): return int(self) < other or int(self) == other
def add(self, other): return int(self) + other
def radd(self, other): return int(self) + other
class D6(Die): def init(self, value=0): super().init(sides=6, value=value)
This is the error message...
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/treehouse/workspace/yatzy/dice.py", line 40, in init
super().init(sides=6, value=value)
TypeError: init() got an unexpected keyword argument 'sides'
Any suggestions? Thanks in advance.

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

2,062 PointsThanks, Steven. I've updated the code but a new type error occurs...

I'm guessing that 2nd one was meant to be "__int__" (for integer conversion) instead of "__init__" (for instance construction).
