What is "self" used for?

Question

I see it almost everywhere in python codes, in situations like "self.something" or "something(self)" It is something involving the scope of the variables?

Answer 1

It's the currently instantiated object.

The difference is not completely explained in the course (nor here) but basically comes down to: In Python you can execute code inside a class without creating an object for it; it's a static copy (and 'self' is nonsense). Once you create an object you can have copies; each copy needs to know to reference its own state and nobody else's.

Answer 2

Self represents the instance of any class. Actually self is just a word. You can write anything instead of "self". The important thing is the first parameter of init method always represents the instance. For example these are same things:

def __init__(self)
self.attribute

def __init__(anyword)
anyword.atrribute

Answer 3

self means it will pass the instance of a class as a argument to the function where it is being called using self
