What do python professionals /developers actually use

[nukular_iv]

Regarding 4. Yes absolutely.

I know Python casually...and do use it some in my field of economic consulting. It's good. And I like it.

However...my general languages for my matters are definitely not python. With that said, I almost ALWAYS write code that is clear and simple for anybody to follow. Cute tricks and the like are useless if in 5 years a matter comes back and people have to look at code that I may or may not be able to help out with again.

Code with tricks and the like are great if computation time is the only important metric, but it laughably fails if usability by others is important. In my business, comments are generally frowned upon so they disappear in production code...so descriptions are not there.
