注意,虽然Exception是所有内置异常类的基类,但还有一些异常不是从Exception派生的(例如SystemExit, KeyboardInterrupt和GeneratorExit)。要真正捕获所有异常,你可以使用BaseException: try: risky_operation() except BaseException as e: handle_all_exceptions(e) 获取异常的详细信息 当你捕获一个异常时,可以通过异常对象...
直到接收到结束信号。当你按下Ctrl+C时,会触发KeyboardInterrupt异常,并在except块中捕获。你可以在这里执行任何必要的清理操作,并在finally块中确保程序优雅退出。 如果你需要从另一个Python脚本或命令行向这个进程发送结束信号,可以使用以下代码: python import os import signal # 假设你要结束的进程PID为1234 target...
You may also notice that an unhandledKeyBoardInterruptexception has caused the program to crash. This happens if you use theCtrl+Ckeys to terminate the code. Because you didn’t catch theKeyBoardInterruptexception, your code had no option other than to crash out. Perhaps you could try handling...

I am desperately looking for a hint how to properly implement a keyboard interrupt (ctrl-c) in a way that on_connect and last_will will get respected. I searched a lot but have not found any hint. At the moment using the code below, whenever I press ctrl-c, the program exits correct...
