Python 2.73
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!
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。同样64位，一个是Win7，一个是Win8
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())
您可以将该代码放入一个文件中，以便在交互式会话启动时自动运行，然后将环境变量 PYTHONSTARTUP 设置为该文件的名称：
