13,163 PointsI 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)

instead of dice.D20().value
.
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 Hand.roll()
method.
Post back if you need more help. Good luck!
