python 强制退出脚本 命令 python怎么强制退出程序

您应该看看Python Signal Handlers(特别是signal.CTRL\u\u事件). 

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。

#!/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"
