Rpg-roller pt 2
So I looked at the other questions for this one but I seem to be the only person getting a 'Hand' doesn't have a 'roll' method error. I see the method right there is this a bug?
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)
from dice import D20 class Hand(list): def __init__(self, size=0, die_class=None, *args, **kwargs): super().init() for _ in range(size): self.append(die_class()) def __len__(self): return super().__len__() @property def total(self): return sum(self) @classmethod def roll(cls, size): return cls(size, D20)

The message might be misleading.
But when you call the base's "
__init__" method, you spelled it "
init" (without the "dunders").
Also, you shouldn't need to override the "
__len__" method just to call the base's. Access to the base methods should be automatic.
