5,586 PointsNeed help in finding the diference
I have attached two pieces of code, one from myself and the other from someone else on the forum. I wasn't able to pass the task with my code but with the other code. The only difference I find is using different types of loop. Can anyone explain to me what I am doing wrong?
Question: 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. I should then be able to call .total on the instance to get the total of the two dice.
I'll leave the implementation of all of that up to you. I don't care how you do it, I only care that it works.
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):
@property
def total(self):
return sum(self)
#my code
@classmethod
def roll(cls, num_roll):
result = []
for _ in range(num_roll):
new_roll = D20()
result.append(new_roll)
return cls(result)
#borrowed code
@classmethod
def roll(cls, no_of_dice):
dice_list = []
count = 1
while count <= no_of_dice:
new_die = D20()
dice_list.append(new_die)
count +=1
return cls(dice_list)

231,275 PointsYour code appears to be a correct solution. So I tested it by pasting it directly into the challenge and it passed.
Perhaps there was a typo in your submission that doesn't appear here?
