I wrote the below code

    def debug(signal, frame):
        'Interrupt    running    process    and    provide    a    python    prompt    for\n                                interactive    debugging.'
        d = {'_frame': frame}
        d.update(frame.f_globals)
        d.update(frame.f_locals)
        i = code.InteractiveConsole(d)
        message = 'Signal    received    :    entering    python    shell.\nTraceback:\n'
        message += ''.join(traceback.format_stack(frame))
        i.interact(message)
    signal.signal(signal.SIGUSR1, debug)
