In this video reviewed three versions of Python decorators: 1. A simple decorator for a function that not accepting any arguments 2. A decorator for a function that accepting some arguments 3. A decorator that has own arguments for a function that accepting some arguments And a small bonus: A small demo that list comprehensions are faster than a FOR loop for generating lists. Python Decorators are possible because of Python functions are first class objects. First class object means that: functions are real objects that even have own methods a function can be assigned as a value to variables a function can be sent to another function as an argument (like it happens with the map() function) we can return function objects as a returning value of another function inside a function we can define another... nested function.
