Console Application Service Unix Python?

Question

linux

Tell me if there are any libraries for creating console applications for unix systems in python?
He is interested in how to design a console application as a unix service
The task is to run the application as a service using system.d,
it spins does nothing, we write the name of the nameService service in the terminal
and it opens, as it were, a session with a console application or something in a new thread, like this trace?
+ surely there are ready-made solutions that automatically auto-complete the command, or do
you need to somehow build a solution so that the environment does it itself? (it seems that you can prescribe command completion in bashrc)
Thanks in advance
