I changed another way for solving this, but it prompt Didn't get D20's...I also ran it in my Pycham, it works, but not h
my code in Pycham works, but here not!
logic is like this:
1, create classmethod, pass parameter "times" to it, and this method returns cls(times), 2, the result returned from classmethod cls(times), pass "times" to constructor init(self, times) to initiate an new instance of Hand class 3, using property to get sum of instance list: lst = Hand.roll(2) lst.total
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)
import dice class Hand(list): #when initiation self is always empty def __init__(self, times): #super().__init__() for _ in range(times): self.append(dice.D20().value) @classmethod def roll(cls, times = 0): return cls(times) @property def total(self): return sum(self)

You are very close! You're code would pass if you used
dice.D20() instead of
Note this solution change fundamentally changes
Hand in that it is either empty or only contains instances of D20. While this works for the challenge, can you organize it so any dice time can be use? Hint: you do not have to create a
Hand.__init__ method. It can be solved entirely within the
Post back if you need more help. Good luck!
