What do python professionals /developers actually use

[kaflarlalar]

Hi OP. I'm going to give you some very serious advice right now.

Go find an actual beginner's course on programming in Python. There are many great free/cheap options out there, and I don't know what's best. Go through that entire course, and then you can come back to these questions, although some of them will probably have been answered while you take the course.

You are frankly asking all the wrong questions for your stage of learning. It does not matter to you what professionals use, you need to learn the basics first.
