Have you ever read the chapter on Decorators from Design Patterns? I’d recommend that for a full treatment, but basically it’s just a way of letting you add on additional work for a function call to do. If we had a decorator called @log(), and a function add_two, if we added this decorator on to add_two it will log the function call or some other aspect(as we define it.)
