Prevent Windows from locking by simulating keypress | Python

windows_no_lock.py

## This script will simulate a keypress and prevent Windows from locking

import pyautogui
import time

def no_lock(button):
    try:
        print ('Press CTRL+C to stop.')
        while True:
            pyautogui.press(button)     # Key pressed
            time.sleep(2)

    except Exception as ex:
        print ('no_lock | Error: ', ex)

def main():
    try:
        print ('\nPrevent Windows screenlock')
        kb_button = str(input('Enter keyboard button: '))
        
        print ('\nRunning')
        no_lock(kb_button)

    except KeyboardInterrupt:
        print('\nStopped')

    except Exception as ex:
        print ('main | Error: ', ex)

if __name__ == "__main__":
    main()

pyautogui.keyDown(button)  # Key pressed
time.sleep(2)
pyautogui.keyUp(button)     # Key released

Thanks for reminding me, the second,
pyautogui.keyUp(button) # Key released
is not required, it was a stupid mistake from my side (didn't go through the documentation completely).
