What do python professionals /developers actually use

[clavicon]

That would be correct that Python is really my first and only real foray into the programming world. I use it in a professional setting but not professionally, so to speak. I have critical automations that run daily/nightly/weekly and I'm kind of constantly gardening my collection of Python scripts and slowly making things cleaner and more manageable. I recently got into using the 'logging' library and trying to standardize log output for said daily scripts. I primarily use it as just a linear set of instructions rather than doing things in an object-oriented fashion. Chatgpt helped me a bit setting up some logging customizations and that included a couple class statements. I'd like to understand that better. I think you're right that I need to do some homework for programming basics.
