How should I continue to make my Hand class working?
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):
super().__init__()
@classmethod
def roll(number):
Hand = []
for rolls in range(number):
Hand.append(int(D20()))
return Hand
@property
def total(self):
return sum(self)

230,995 PointsYou're getting close, here's a few hints:
- the "super" call that's sitting there by itself isn't needed
- a class method would generally have a first parameter of "cls"
- the "roll" method should return an instance of the "Hand" class instead of a list
- the D20's should be appended directly and not converted into ints
