Use thetry...exceptStatement to Catch theKeyboardInterruptError in Python Thetry...exceptstatement is used when it comes to the purpose of exception handling in Python. Thetry...exceptstatement has a unique syntax; it is divided into three blocks, all of which have a different purpose and ...

在Python中,异常处理是通过try...except语句来实现的,而不是像某些其他编程语言(如Java)那样使用try...catch。尽管没有直接的“catch”关键字作为独立的语句,但Python的异常处理机制非常强大且灵活。以下是如何在Python中使用try...except来处理异常的详细指南: 基本用法 try: # 尝试执行的代码块 risky_operation(...
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...
这捕获了大多数异常,但忽略了您几乎永远不想捕获的SystemExit和KeyboardInterrupt,除非可能在程序的顶层。 (3认同) pan*_*kaj 27 虽然其他答案和接受的答案是正确的,应该在实际代码中遵循,只是为了完整性和幽默,你可以尝试fuckitpy(https://github.com/ajalt/fuckitpy)模块. 您的代码可以更改为以下内容: @...

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...

【Python】异常处理,try、catch、else、finally 基本形式: 异常分为系统预定义异常和自定义异常。 预定义异常: 异常名称 描述 BaseException 所有异常的基类 SystemExit 解释器请求退出 KeyboardInterrupt 用户中断执行(通常是输入^C) Exception 常规错误的基类 StopIteration 迭代器没有更多的值 GeneratorExit 生成器(gener...
