📌 What You Will Learn

Understand what self represents inside a class
Know where self is used: constructors and instance methods
Access instance variables and methods using self
Remember that self must always be the first parameter

self is the reference to the current object inside a class.

It is used to access instance variables and instance methods.

Inside constructors
Inside instance methods

Inside the constructor, self.name stores the name in the current object, so each object keeps its own value.

🐍Code Cell

Term	Meaning
self	Current object
Instance variable	Variable tied to object
Instance method	Method that uses self

📝 Key Takeaways

self is the reference to the current object inside a class
It is used to access instance variables and instance methods
self is used inside constructors and inside instance methods
It must always be the first parameter of an instance method or constructor
