python怎么强制退出程序什么键_如何防止Python脚本强制退出？

您应该看看Python Signal Handlers(特别是signal.CTRLuu事件). 在

这里有一个更完整的答案。。。注意：通过使用这些东西，您可以使您的过程变得相当不可更改。在#!/usr/bin/env python

import signal, os

import time

def handler( signum, frame ):

print "Signal handler caught", signum, "@", time.ctime()

if signum == 2:

raise "Caught Signal 2 - Exiting"
