In Python, a decorator is a design pattern that allows you to
 modify the functionality of a function by wrapping it in 
 another function. The outer function is called the decorator, 
which takes the original function as an argument and returns
 a modified version of it123. Decorators provide a simple 
 syntax for calling higher-order functions1.


 However, to understand decorators, it is enough to think 
 about functions as something that turns given
  arguments into a value.
