Godot Python Export? (Or c++?)

Godot Version

3.5.1

Question

I know there is a plugin for python but it is very difficult to use.
Is there is a better solution for godot python?
I mean to say for example you can use python libs on your project and you can export your project to any platform (pc-mobile all) and it works if the device doesnt have python also. If its possible or not?

And same for c++ also?
for example you can use c++ libs on your project and you can export your project to any platform (pc-mobile all) and it works. If its possible or not?

Godot is written in C++ so you can just get the source code and do your stuff. Gdscript’s syntax is very python like, just try it, since it perfectly embedded into the engine. And from here you can export it to android or windows.

Thanks for repyl @thomas,

I am so sorry but I cant understand what do you mean here?

You just need Godot, everything you need is in there.

maybe you didnt understand my question. Yes godot have so many features but for example you want to show pdf files in godot. I cant find a way to do it with godot. But if you use a python library with godot maybe it can work. Like that situations users can want to use python libs with godot. Or if python cant, then maybe c++ because of godot written with it. You cant say everyone to if u want then recompile engine. I am looking for another way.
