如何使用 Python 在命令行中创建交互式应用程序，而不仅仅是返回 output 的脚本？

Question

I would like to make a command line application in Python which, when I call its name, launches a new "mode" or interface at the command line, like launching Vim or Mutt, where key presses like 'q' or 'y' have specific functions - rather than just a script you run which returns some output.

How do I make this? Is there a specific library I would use for making this application? Or are there specific commands that tell the shell to display a kind of "window", and to listen for key presses and to execute commands on them?

You can take a look at this question , there are some useful advices. In particular the best option seems to be the curses extension module .

I suggest also to check out this project that can give you an useful example to do what you ask, even if it uses a GUI kit.
