Understand and Master the Decorator in Python

A decorator is a function that takes another function as input, extends its behavior, and returns a new function as output. This is possible because, in Python, functions are first-class objects, which means they can be passed as arguments to functions and also be returned from functions, just as other types of objects such as string, int, or float.
