3,241 Pointspython: dice-roller/rpg-roller 2/2 | Error
Im having the following error:
AttributeError: 'list' object has no attribute 'total'
I google it and the problem seems to be that function catch a list an it can't be process in the @property method.
im a little stuck here :/
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, sides=20):
super().__init__(sides)
from dice import D20
class Hand(list):
def __init__(self, size=0, die_class=None, *args, **kwargs):
if not die_class:
raise ValueError("You must define a dice class")
super().__init__()
for _ in range(size):
self.append(die_class())
self.sort()
# Now update Hand in hands.py.
# I'm going to use code similar to Hand.roll(2)
# and I want to get back an instance of Hand with
# two D20s rolled in it.
@classmethod
def roll(cls, dice):
dr = []
for _ in range(dice):
dr.append(cls(size=2, die_class=D20))
return dr
# I should then be able to call .total on the instance
# to get the total of the two dice.
@property
def total(self):
data = self
return sum(data[0])

override for this challenge, but if you do you must be careful not to change the method signature.
In particular you should not make any arguments mandatory for creating a new instance, since none were needed before.
