Python is included in all major Linux distros, just open a terminal and type "python3 --version", so no need for RPI, especially not the zero as it is way to slow.
For non essential stuff, vibe coding is fine and will save a lot of time, but being able to actually audit the code is a very nice bonus.
Claude has become pretty damn good at it, and so are some smaller models you can run locally on your PC, and Gemini is also very good at Python, it is free, so give it a try.
Despite what the internet would have you believe, you can run local models even on some low spec PC's and laptops, quite comfortably, and having a GPU with 8GB or more makes it way faster than you can read (that is my personal benchmark), and AMD APU's (GPU+CPU) are very good st it, i have Ryzen 7 laptops (3 of them) and they can run 4B parameter models exceptionally good, 7B and 8B with a bit of tweaking, all on 16GB of total memory.
Download LM Studio, download some 3-6GB models, play with them, you might be pleasantly surprised.
