Python decorators are a very useful tool in python and used to enhance the functions and classes’ functionality and behaviour. If we want to modify the behavior of the existing function without modifying the original function, then we can use decorators to alter its behavior, and we can also ...
Decorator examples in Python Let’s now quickly go through some of the Python decorator examples. It is essential to practice with live code to increase your understanding of this concept. Simple program to demonstrate decorator def decorate(func): def first(): func() print("This is the First...

Decorating functions with parameters The following examples show how to decorate functions which take parameters. main.py #!/usr/bin/python def enclose(fun): def wrapper(val): print("***") fun(val) print("***") return wrapper @enclose...
The only constraint on the result of a decorator is that it be callable, so it can properly replace the decorated function. In the above examples, I've replaced the original function with an object of a class that has a__call__()method. But a function object is also callable, so we...
Next, we'll illustrate how you can define a function inside another function in Python. Stay with me, we'll soon find out how all this is relevant in creating and understanding decorators in Python. def plus_one(number): def add_one(number): return number + 1 result = add_one(number...
In Python, the @classmethod decorator is used to declare a method in the class as a class method that can be called using ClassName.MethodName(). The class method can also be called using an object of the class. The @classmethod is an alternative of the classmethod() function. It is re...
