How to host your code online to run 24/7
I've got as far as working out (I think) that I can install VScode on the raspberry pi and run the code from there but idk how that works really and seems like a work around rather than doing it "correctly"? You don't need VS Code to run code. It's a development tool, not a runtime. All you really need to do is put a copy of your program on the Pi, create a virtual environment and install your dependencies in it, start the program, and then you can leave it be. You can optionally set it to run your program on start-up if you want it to restart automatically in case the power cuts off for a moment. More on reddit.com

Online code compiler for C++, Java and other programming languages.

Cool that it can execute the programs it compiles.

Assembly language being called assembler is a pet peeve of mine though.
It's like calling C++ "compiler".

r/learnpython on Reddit: How to host your code online to run 24/7
March 25, 2024 -

Not sure if I should post this here or elsewhere but I'm learning python so I'll go with it for now.

I've at the point were I would like to have some of my code running as close to 24/7 as possible, obviously I don't want to run it on my pc because that seems silly.

I know the options are something like: My pc A home server (raspberry pi?) Online hosting

I took a look at AWS but I got so confused straight away and I couldn't really get my head around any videos or literature on how to do what I wanted.

I'm leaning towards a raspberry pi as I have a raspberry pi 4 already sitting next to me doing nothing but again have no idea where to start to set it up.

I'm not wanting to host a website, I just want my code to run, what actual options are possible and how would I go about setting it up?

I've got as far as working out (I think) that I can install VScode on the raspberry pi and run the code from there but idk how that works really and seems like a work around rather than doing it "correctly"?

I'm sorry if this info can be found elsewhere, honestly I've tried but I couldn't come up with much.

Thanks in advance.
