CHALLENGE:
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, sides=20):
super().__init__()
self.sides = sides
import dice
class Hand(list):
def roll(x):
for _ in range(x):
return(D20.value)
@property
def total(self):
return sum(self)

- need to decorate
roll
with@classmethod
- need to include
cls
as the first parameter in a classmethod - need to create an instance of
Hand
to return. Useself = cls()
- with
self
as the instance, you can appenddice.D20()
instances within loop - need to use
dice.D20()
instead ofD20()
since onlydice
was imported -
return
needs to be outside of thefor
loop or only first pass is run before returning - return
self
as the created instance.
Post back if you need more help. Good luck!!
