background process - How to keep a python script idle without using too many ressources

Question

Basically the title, i have a small python script (python 3.9, Windows 10) that i would like to keep running in the background. It is currently listening for keyboard hotkeys and acting like a macro engine. I want it to stay idle, since i use the keyboard module so i doesnt need to call anything, just wait.
I tried a while loop with either pass or sleep in it, but both have downsides, the one with pass using a lot of cpu ressources, and the one with sleep being very unreliable.

Is there any pretty/good practice way of doing this ?

Answer 1

I would suggest to use some library that does the trick for you.

For example you can try Asyncio:

import asyncio 

loop = asyncio.get_event_loop()
try:
    loop.run_forever()
finally:
    loop.close()

Here's an Asyncio example for keypress.
