TypeError: attack() missing 1 required positional argument: 'self'

Question

hi im getting this error

TypeError: attack() missing 1 required positional argument: \'self\'

and this is my code

class En         


        

Answer 1

You need to create and use an instance of the class, not the class itself:

enemy = Enemmy()

That instance is then accessible as self. If you don't have an instance, then it's missing and that's what the error message tells you.

Answer 2

You're not instantiating your Enemy class. You are creating a new reference to the class itself. Then when you try and call a method, you are calling it without an instance, which is supposed to go into the self parameter of attack().

Change

enemy = Enemy

to

enemy = Enemy()

Also (as pointed out in by Kevin in the comments) your Enemy class should probably have an init method to initialise its fields. E.g.

class Enemy:
    def __init__(self):
        self.life = 3
    ...
