python捕获ctrl+c中断的两种方法

1，try…except…

    try:
        while True:
            time.sleep(100)
    except KeyboardInterrupt:
        print('Got signal: SIGINT, shutting down.')
        exit(0)

2, 信号处理

def handler(signal_received, frame):
    # Handle any cleanup here
    if signal_received == signal.SIGINT:
        print('SIGINT or CTRL-C detected. Exiting gracefully')
        exit(0)
if __name__ == '__main__':
    signal.signal(signal.SIGINT, handler=handler) # ctlr + c

建议用try…except的方法，通用性强，代码易读性高。
