How can I make the script run all the time?

Question

Python

In general, the question is
I have a file with a voice assistant which I wrote in python. It uses the gTTS library for speech playback. After starting the file, it listens and if there are keywords, it performs some function and after that the file execution ends.
How to make it so that the execution does not end?

Answer 1

Here is an example to study, 2 functions are executed independently of each other. For example, one with an infinite loop, the second with a finite one, the first will continue to be executed regardless of the fact that the second has ended.

from threading import Thread
from time import sleep


def print_some1(txt):
    while True:
        print(f'{print_some1.__name__} - {txt}')
        sleep(.5)


def print_some2(txt, n):
    while n < 10:
        n += 1
        print(f'{print_some2.__name__} - {txt}')
        sleep(.75)


if __name__ == '__main__':
    text = 'some text message'
    Thread(target=print_some1, args=(text,)).start()
    Thread(target=print_some2, args=(text, 1)).start()

Answer 2

I don't know how your code works, but I suspect that you need to listen in an infinite loop, running functions in separate threads.
