Refresh data in python script while running in Terminal

[Larz60+]

You need to use an event timer. It will run independent of other precesses, and create an event (interrupt) when the terminal time is reached.

here's a quick example:

import threading, time


def do_work():
    print("OK ... I'm doing my work here")   

def testit(seconds):
    timer = threading.Event()
    while True:
        print(f"delay {seconds} seconds")
        timer.wait(seconds)
        do_work()


if __name__ == '__main__':
    testit(2)

sample output:

Output:
delay 2 seconds
OK ... I'm doing my work heredelay 2 seconds
OK ... I'm doing my work here
delay 2 seconds
OK ... I'm doing my work here
delay 2 seconds
OK ... I'm doing my work here
delay 2 seconds
delay 2 seconds
OK ... I'm doing my work here
delay 2 seconds
OK ... I'm doing my work here
delay 2 seconds
