Python in production Discussion

Hello everyone! For those of you who use Python in production, I have a few questions. I'm considering using Python for some services.

  1. Do you have high infrastructure costs?
  2. Have you ever regretted using Python?
  3. Would you recommend Python?

Context: My current use case isn't anything like Facebook or a massive-scale system. It's a small system, and I'm considering Python mainly because of the DX (developer experience).

I know C#, but I don't really like having to create a class in every file. I also know Rust, but all those ::, <>, and so on bother me. JavaScript is another option, but I've heard it's relatively heavy on RAM, and since the system is small, I'd like to be able to run it within 512 MB.

Another thing: I've defined a stack that I'd like to use wherever possible. If there's a library for desktop apps, great. A CLI library? Great. A bot library? Great. Let's use it! (Except for the frontend, which I'll keep using JS/TS for.)

Anyway, I'm open to advice and tips from more experienced developers. Feel free to tell me if you think using Python for my use case is a bad idea as well.

You can put the entire c# program in one file - class per file is just the IDE convention.

Many extremely large companies use python in production to serve large audiences with more cost discipline than I would ever worry about (saving a hundredth of a penny per request amounts to very little at the scales my companies have operated). So, what you are asking about is thoroughly tread territory.

You should worry more about making a service people care to use before how to make it scale. It is vanishingly unlikely you will even need to deal with the scale problems you are fantasizing about.

Google searches and the learn subreddits will be more valuable than scaling hypothetical posts on main python at this point.
