Python Decorators with a real life example

In this introductory tutorial, we’ll look at what decorators are and how to create and use them. Decorators provide a simple syntax for calling higher-order functions. By definition, a decorator is a function that takes another function and extends the behavior of the latter function without explicitly modifying it. Sounds confusing – but it’s really not, especially after we go over a number of examples.
