Catch KeyboardInterrupt

  • 772

I'm doing one aplicación cliand I need to capture one KeyboardInterrupt at any point in the execution of the program.

My intention is to eliminate some folders/files that may have been generated.

Is there any solution cross-platform?

python

    If I understood you, you could use the signalstandard library module that allows us to capture certain events asynchronously. Although there are some details of this module that are not cross-platform, in this case you should not have problems.

    However, it is important to note that it can only be used on the main thread if you are using a multi-threaded application.

    This would be a simple example:

    import signal
import sys
import time

# Función que se ejecutará cuando el evento tenga lugar.
def keyboard_interrupt(signal, frame):
    print('Has precionado Ctrl + c')
    sys.exit(0) # Si quieres detener la ejecución

signal.signal(signal.SIGINT, keyboard_interrupt)


def run():
    while True:
        time.sleep(1)


if __name__ == "__main__":
    run()
