Introduction One of the coolest features of Python is its nice ability to create decorators. In short, decorators allow us to modify how a function behaves without changing the function's source code. This can often make code cleaner and easier to modify. For instance, decorators are also really useful if you have a collection of functions where each function has similar repeating code. Fortunately, decorators can now also be created in R!

Below we have a function that prints today's date. In our example, we create two functions. The first - print_start_end takes another function as input. It…
