Can only Python be used to create a new Operating system??
https://www.sololearn.com/discuss/2090583/?ref=app tl;dr Python can't be used. Not by itself, at least.
That is extremely untrue. Operating systems are basically a software that bridges between different hardware. For example ram, storage disks, monitors keyboards and more. To program a software that has access to these attributes there is a language called assembly. Although, some languages have libraries that allow you to interact with hardware. To explain better what assembly is, have a big, long look at the very known file extension called dll.
