How can I implement the @property decorators to achieve this code challenge hands.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

    def __add__(self, other):
        return int(self) + other

    def __radd__(self, other):
        return self + other

        if not die_class:
            raise ValueError("Must provide a class")
        super().__init__(sides=20)
