Let’s say I have set up two files.

One is main.py:

from .terminal import current_instance

current_instance.addstr("Hello world!")
current_instance.refresh()

Other is terminal.py:

import curses

current_instance = curses.initscr()
curses.noecho()
curses.cbreak()

When I run main.py, the window is initiated, text printed, but after that the window closes and quits the program. If I try to put a loop in terminal.py, it’ll just block the program, and putting a loop in main.py would be inconvenient as I have other files that should also output text to the terminal window.

So is it possible to make the window “persistent”, while being non-blocking?

I tried calling nodelay() and making an asynchronous function that calls getch() infinitely, and while the window is persistent, the function is still blocking.
