I want to know what's wrong in my code. A set of 2 die are rolled and random values are printed

I made a code for generating random values when a set of 2 die are rolled. Error says roll isn't defined. Can't figure out why it says that. I want to know what's wrong with my approach, I've already seen other solutions to the problem.

Novice programmer. My first problem related to generating random values.

import random
class Dice:
    def roll(self):
        roll = (1, 2, 3, 4, 5, 6)

toss = random.randint(roll)
print(toss, toss)
toss = random.randint(roll)

Error :

NameError: name 'roll' is not defined
