how to make an os in python

nfortunately Python is classified as a very high level programming language. It cannot be used, for example, to directly access hardware and perform low-level data structure manipulation. It is completely dependent on something to abstract the hardware from it, and that is the Kernel. It is, however, technically possible to create an operating system centered on Python, that is; have only the very low level stuff in written in C and assembly and have most of the rest of the operating system written in Python.
