11,906 PointsGetting a message that a class method doesnt exist
Why is it that i get an error message when i check this? It says that class "Hand" does not have a roll method although it does. When i test the code on my computer it works as it should.
import random
class Hand:
def __init__(self, rolls):
self.dice_list = []
for i in range(rolls):
self.dice_list.append(D20())
@classmethod
def roll(cls, rolls):
return cls(rolls)
@property
def total(self):
return sum(self.dice_list)
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)
class Hand(list):
@property
def total(self):
return sum(self)
