25. Decorators [Python 3 Programming Tutorials]

In this tutorial, I explain decorators in a very simple way by going over how to measure execution time of function using decorators. They serve as a wrapper to original function but does a wonderful job of avoiding code duplication and not cluttering original code with additional logic.

@Codebasis, out of curiosity, could we replace *args and **kwargs by parameters?, if so, how could we do it?.

I had a doubt here wrapper function return result but to which function it's going to return. Can you please clear this doubt.

[elliekongnamul]

Thank you for the video! It has been really helpful. Just want to ask one question though. Why time_it method needs to have a nested method, wrapper? what time_it does is to have wrapper function and nothing more. Is there something I missed understanding?

[brightenglish]

why did you use *args and **kwargs in wrapper ?

[debojitmandal]

Str((end - start) how is it even possible to write this bcs these two parameters with - in between is not defined
