为什么当我按 CTRL + C 时在笔记本电脑上显示为什么，我可以退出解释器并在桌面上按 CTRL + C 将使解释器向我发回KeyboardInterrupt消息.我该如何摆脱这个KeyboardInterrupt并回到 CTRL + C 退出！

Why is it on my laptop when I hit CTRL+C, I can exit the interpreter and on my desktop hitting CTRL+C will make the interpreter shoot back at me a KeyboardInterrupt message. How can I get rid of this KeyboardInterrupt and go back to exiting with CTRL+C!

在我的桌面上，需要输入 CTRL + Z 并按Enter退出.

On my desktop it's required to input CTRL+Z and hitting enter to exit.

我在两台计算机上都使用PowerShell.相同的64位，一个是Win7一个是Win8

I am using PowerShell on both computer. Same 64bit, one is Win7 one is Win8

推荐答案

您可以将 CTRL - C 的信号处理程序更改为退出解释器的内容:

You could change the signal handler for CTRL-C to something that exits the interpreter:

import signal
import sys
signal.signal(signal.SIGINT, lambda number, frame: sys.exit())

您可能会将代码放在一个交互式会话开始时自动运行的文件中，然后将环境变量PYTHONSTARTUP设置为该文件的名称:

You could probably put that code in a file to be run automatically when an interactive session starts, then set the environment variable PYTHONSTARTUP to the name of that file:
