如何覆盖键盘中断？ （蟒蛇）

Question

无论如何，当脚本运行时，当我Ctrl+c时，我可以让我的脚本执行我的一个功能吗？

Answer 1

看看信号处理程序 。 CTRL-C对应于SIGINT （posix系统上的信号＃2）。

例：

#!/usr/bin/env python
import signal
import sys
def signal_handler(signal, frame):
    print 'You pressed Ctrl+C - or killed me with -2'
    sys.exit(0)
signal.signal(signal.SIGINT, signal_handler)
print 'Press Ctrl+C'
signal.pause()

Answer 2

当然。

try:
  # Your normal block of code
except KeyboardInterrupt:
  # Your code which is executed when CTRL+C is pressed.
finally:
  # Your code which is always executed.

Answer 3

使用KeyboardInterrupt异常并在except块中调用您的函数。
