How to pass atributes to a method in a class in Python?

Trying to get the hang of classes, can anyone tell me how to get my method "attack" to add the baseDamage to the damage? currently it just prints the "damage" and doesn't add the baseDamage to it.

from random import randint

class Weapon:
    def __init__(self, name, baseDamage, price):
        self.name = name
        self.baseDamage = baseDamage
        self.price = price
    def attack(self):
        damage = randint(1,10)
        self.baseDamage + damage
        return damage

def main():
    steelSword = Weapon("Steel Longsword", 10, 250)
    print("Name:", steelSword.name, "\nDamage:", steelSword.baseDamage, "\nPrice:", steelSword.price,"coins")
    print(steelSword.attack())

main()

You need to assign your new value back to self.baseDamage. Your line here:

self.baseDamage + damage

Is not storing the result anywhere. To do this, you want to assign it back to self.baseDamage like this:

self.baseDamage += damage

To expand that, it is similar to writing it out like this: 

self.baseDamage = self.baseDamage + damage

You could even further simplify and do this: 

self.baseDamage += randint(1,10)

Also, you should make sure what it is you want to return. If you return damage, you are not returning the "baseDamage + damage". Maybe you want to return self.baseDamage after you performed your attack calculation?

self.baseDamage += damage

OR

self.baseDamage = self.baseDamage + damage
