4,693 PointsI'm not sure why my code isn't passing.
I'm referring the hands.py file. Below is the class I wrote. I've run this with the interactive prompt on my computer and it runs fine. Maybe I'm missing or not understanding a requirement? It would be helpful if you actually got the reason for he bummer and not just "Try again".
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)
class Hand(list):
def __init__(self, size = 2):
super().__init__()
for _ in range(size):
self.append(D20())
@classmethod
def roll(cls, rolls):
return cls(size=rolls)
@property
def total(self):
return sum(self)

231,275 PointsI can think of two issues you may be having. First, "hands.py" probably needs this:
from dice import D20
Then, the new code shouldn't modify how "Hand" works when not using "roll". But previously, a "Hand" instance created with no arguments would be empty. With this code, it would have 2 D20's in it.

4,693 PointsThis was right on. I had forgotten to import dice.
