Question

Explain the importance of self in Python classes.

Answer 1

• self refers to the current instance (object) of a class.
• It is the first parameter of every instance method, including __init__.
• It is used to access or modify instance attributes and call other instance methods.
• Python passes it automatically during a method call.

class Demo:
    def show(self):
        print("Object method called")


d1 = Demo()
d1.show()          # Python internally uses Demo.show(d1)

self is not a reserved keyword, but it is the standard Python convention.
