dice.py
```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

return int(self) + other

return self + other
class D20(Die):
def __init__(self, sides = 20):
super().__init__(sides)
class Hand(list):
def __init__(self, size=0, die_class=D20):
self.size = size
super().__init__()
for _ in range(size):
self.append(die_class())

@classmethod
def roll(cls, size=2):
return cls(size)

@property
def total(self):
return sum(self)
```
hands.py
```class Hand(list):
@property
def total(self):
return sum(self)
``` Then, you should import `dice.py` in `hands.py` with a line
```import dice
