TIL_Decorator in Python

In Python, a decorator is a special type of function that modifies or extends the behavior of other functions or methods. It's used to apply common functionality to multiple functions without duplicating code.

 

 

You can use a decorator as below,

def hello_decorator(func):
	def wrapper():
    	print("Here's the before the function is called.")
        func()
        print("Here's the after the function is called.")
    return wrapper
    
    
@hello_decorator	#Decorator
def hello():
    print("Hello!")
    
    
hello()    #call the hello function

 

 

Since using the decorator called 'hello_decorator', you'll get the print like this.

Here's the before the function is called.
Hello!
Here's the after the function is called.

 

 

What are the benefits to use Decorator in Python?

• Code Reusability
• Modularity
• Readability

 

 

Decorators in Python contribute to make the code cleaner, more modular, and more readable by promoting code reuse, and providing consistent and flexible way to extend the behavior of functions or methods.
