Decorators: simple example

• A decorator is that @something just before the declaration of the function.
• Decorators can modify the behavior of functions or can set some meta information about them.
• In this book first we’ll see a few examples of existing decorators of Python and 3rd party libraries.
• Then we’ll learn when and how to create our own decorators.
• Then we’ll take a look at the implementation of some of the well-known decorators.

def some_function():
