Python decorators are a powerful feature that allows you to modify or enhance the behavior of functions or methods. They provide a way to add functionality to existing code without modifying it directly. Decorators are widely used in Python for various purposes such as logging, caching, authentication, and more.

Just remember these don’t destroy any of your existing code, but rather apply additional functionality or behavior to your existing code. Giving a portion of your code increased benefits in the moment they need it the most.
