Code works locally, but doesn't pass the test. Feedback isn't verbose, so not clear what's up.

This seems to fulfill the specifications, and works on my local machine, but apparently isn't "correct." Anyone know what's going on?

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

Hi asafitch! You have not imported D20 from dice at the top of your hands.py. Once you have, you will get more explicit feedback. Hope this helps, and good luck with your coding! :)

The only problem I can see is that your missing @classmethod before the roll definition. Unfortunately, it seems that it still does not work even if you add that. I am unsure of the reason why, so I'll leave the rest up to somebody else to answer! :confused:
