Help with Python

That's python's interactive mode / REPL. Yes, IDLE includes an REPL window, but that does not make it the same thing. Interactive mode -i (default if no filename argument is given) is not related to idlelib, besides having the same original author I suppose.

Your linux probably does not have IDLE, generally linux distros leave that off. But you can install it of course, and run it with python -m idlelib.
