Why would you use a decorator?

  • A decorator is similar to a class and should be used if you are doing functional programming instead of object oriented programming.
  • A decorator is a visual indicator to someone reading your code that a portion of your code is critical and should not be changed.
  • You use the decorator to alter the functionality of a function without having to modify the functions code.
  • An import statement is preceded by a decorator, python knows to import the most recent version of whatever package or library is being imported.
