Explaining the Difference Between Static, Instance, and Class Methods in Python: A Code Example

Introduction:

In object-oriented programming, we often use methods to define the behavior of an object. In Python, there are three types of methods: static methods, instance methods, and class methods. Each of these methods has its own unique properties and use cases. Understanding the difference between these methods is crucial for writing efficient and effective code. In this article, we will explain the difference between static, instance, and class methods in Python, with a code example.

In this code, we have defined a Person class with three methods: hello(), instance_hello(), and class_hello(). We have also created an instance of the Person class called p.

Code Explanation

class Person:

Here, we define a Person class.

    def hello():
        print("Hello, World!")

This method, hello(), is a static method that prints out "Hello, World!" to the console. It does not take any arguments.

    def instance_hello(args):
        print(f"hello instance {args}")

This method, instance_hello(), is an instance method that takes one argument, args. When called, it will print out "hello instance" followed by the value of the args parameter.

    @classmethod
    def class_hello(args):
        print(f"hello class…
