What is Python for?
I googled it, but it seems too complicated and for experts.
What Animal_OG said. Unrpyc, a tool for decompiling Ren'Py games' scripts, for example, requires Python, but if you never missed it, you don't have to download it.It's a (very general) programming language. You might need to install it to run a few apps even if you don't use it to actively code or develop stuff.
Don't sweat it though, if you think you don't need it just skip it.
