How to learn python to apply it in my work?

[DavyAnt]

Good afternoon!

Background:

I want to increase the speed of data processing, perform analysis, automate processes. All this to increase efficiency in work. My field is external economic activity.
I would like to be able to create parsers and bots to analyze data, as well as scripts to automate tasks.

Question:

I have learned the basic commands. What should I do next? Should I start delving into various libraries? Should I take specialized courses? Should I read some books?

I realize that there is a lot of information and it is not clear where to go next, so as not to lose valuable time on studying what may not be useful later.

I will be very grateful for your answer and expert opinion!

All of the things you mention will help.

Try this:
search google and/or pypi.org for examples that match, or come close, to what you want to accomplish. Find lines of code that you don't understand in the example, and then read up on the commands in that code (python.org) that you don't understand.
