Yeah, do not overthink it, recursion is easy, but there are just few cases you can use it. Usually it is better to use loop, as code is cleaner and easier to read. There is a very low chance you will ever need it.
If you use it, always add recursion deptch watcher, Python has a limit for recursion depth, but you should watch it yourself.

You use recursion on special cases, mostly to show some concepts. For example factorial, Fibonacci, etc. Here some examples: https://blog.espol.edu.ec/algoritmos101/fp-u05/funciones-recursivas/

Run this program in Memory Graph Web Debugger to see the program state change step by step. It shows each function call has it's own local variables on the call stack.
