My answer for pt. 2 won't work because "Can't get the length of a 'Hand'." Yet I ran my code in IDLE and it works as expected. I am able to generate Hand instances and get their lengths without issue. Any ideas why it won't work?
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):
Die.__init__(self, sides=20)
class Hand(list):
def roll(self, numdice):
for _ in range(numdice):
self.append(D20())
@property
def total(self):
return sum(self)

- the challenge expects you to return a new instance, but this code doesn't return anything
- since a new instance is being created, this should probably be a class method
- "
from dice import D20
"
