Static Class in Python

1. Use the @staticmethod Decorator to Create a Static Class in Python
2. Use the @classmethod Decorator to Create a Static Class in Python
3. Use a Module File to Create a Static Class in Python

A static class is a handy feature in programming. A static class cannot be inherited and cannot be instantiated. There is no direct way to make a class static. In Python, we can implement a static class by making its methods and variables static.

In this article, we will implement such methods.

Use the @staticmethod Decorator to Create a Static Class in Python

To implement a static class, we can make its methods and variables static. For this, we can use the @staticmethod decorator to create methods in a class static. A decorator is a special function specified before a function and takes the whole function as a parameter.

For example,

class abc(object):
    @staticmethod
    def static_method():
        print("Hi,this tutorial is about static class in python")


abc.static_method()

Output:

Hi,this tutorial is about static class in python

Note that this method only works on versions of Python higher than 2.6.

Use the @classmethod Decorator to Create a Static Class in Python

The @classmethod can make a method static to the class and not its object. It has several advantages over the @staticmethod decorator. It will also work with subclasses and can modify the class state.

However, it requires a compulsory argument to be included in the method called cls.

See the following code.

class abc(object):
    @classmethod
    def static_method(cls):
        print("Hi,this tutorial is about static class in python")


abc.static_method()

Output:

Hi,this tutorial is about static class in python

Use a Module File to Create a Static Class in Python

In Python, probably the best way to implement a static class is by creating a module. We can import a module, and its functions can be accessed using the module name. It does not require any objects to be instantiated, and it cannot be inherited.

See the following example.

def static_method():
    print("Hi this is the content of the module file")

The above code can be a simple function in a Python script that can be imported as a module.

For example, if the name of the above Python script is abc.py, we can do something as shown below.

import abc

abc.static_method()

Output:
