如何覆蓋鍵盤中斷？ （Python）

Question

是否有反正我可以讓我的腳本執行我的一個功能，當腳本運行時點擊Ctrl+c？

Answer 1

看看signal handlers。 CTRL-C對應於SIGINT（posix系統上的信號＃2）。

例子：

#!/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

使用在except塊KeyboardInterrupt exception和調用你的函數。

Answer 3

當然。

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.
