I have used console.status() from Rich instead of this one.

@dpriskorn, cool "spinner", thanks! I posted "my" spinner with the same motivation as the author of the original gist: to provide an understandable simple short solution that can be implemented into the project without unnecessary dependencies.

👍

In case you need a really sophisticated and beautiful progress bar in a terminal, consider importing the rich library: https://github.com/Textualize/rich

See it in action: https://github.com/Textualize/rich/blob/master/imgs/progress.gif

Also, I used rich for a handy CLI tool that I've made in spare time. Demo and code is here: https://github.com/vladignatyev/bulktag

take it, thanks
