3 lut 2016 · For instance, Windows has Pywin32. Example implementation: import time import win32api def is_pressed(key): x = win32api.GetKeyState(key) return (x & (1 << 8)) != 0 print "Beginning calculation. Press the Q key to quit." while not is_pressed(ord("Q")): print "calculating..." time.sleep(0.1) print "Finished calculation."
6 mar 2024 · Kill a While Loop with a Keystroke Using KeyboardInterrupt. In this example, below code a variable num with 11 and enters an infinite loop, printing and incrementing num by 2 in each iteration until an even number is encountered. The loop is slowed down by one second.
try: while True: do_something() except KeyboardInterrupt: pass. For this the exit keystroke would be ctrl+c. Or if you want to use a module you can take a look at the Keyboard module and use the keyboard.on_press(<your_quit_key>) while True: # Do your stuff.
