To define

In Python, the key difference is that instance methods operate on a specific object using self, while static methods are independent utility functions inside the class that don’t rely on self or cls. Instance methods are tied to object data, whereas static methods are just grouped logically under the class for organization.

class Dog:

    def __init__(self, name):

        self.name = name   # instance attribute

    def speak(self):       # instance method

        return f"{self.name} says: Bark!"

dog1 = Dog("Rover")

print(dog1.speak())   # Rover says: Bark!

---------

class Dog:

    @staticmethod

    def bark_sound():   # static method

        return "Bark!"

print(Dog.bark_sound())   # Bark!

dog2 = Dog("Buddy")

print(dog2.bark_sound())  # Bark! (works, but doesn’t use dog2)
