Linux by python...my dream

Quote:

I want to rewrite the Linux kernel

Bad idea. If there is not millions of Linux written in everyone's favorite language, it is because it is huge and hard, and not every programming language is usable to build an OS.
An OS talks to bare metal, it rely only on services it create itself.
Python is interpreted, and interpreter rely on existing OS.

I'm looking for a C, Assembly, Ruby, Shell programming language converter (if any)

Beyond the most simple programs, consider converters as bad, because different languages have different ways to do the same thing, and OS source code is extremely technical.

Most OS are written in Assembly and C because those languages can talk to bare metal without any service, and they are fast.

Forget it.
Python needs an OS to work: it's an interpreted scripting language which needs the interpreter (which provides the framework for your app to run) to be executing before your app does. And that needs the OS beneath it to provide hardware services before it can run.

Writing an OS in Python would be a "chicken and egg" situation in that the Python interpreter would need your app (the Linux OS) running before it could start, and your app (the Linux OS) would need the Python interpreter running before it could run! :laugh:

You probably need to start by looking at the existing source code at GitHub - torvalds/linux: Linux kernel source tree[^].
