I want to prevent the user from going back to the shell prompt by pressing CTRL + Z from my python command line interpreter script. How can I do that?

推荐答案

您可以为SIGTSTP编写信号处理程序，该信号处理程序由 Ctrl + Z 触发.这是一个示例:

You could write a signal handler for SIGTSTP, which is triggered by Ctrl + Z. Here is an example:

import signal

def handler(signum, frame):
    print 'Ctrl+Z pressed, but ignored'

signal.signal(signal.SIGTSTP, handler)

while True:
   pass
