python tab completion in windows
提问by Nate
I'm writing a cross-platform shell like program in python and I'd like to add custom tab-completion actions. On Unix systems I can use the built-in readline module and use code like the following to specify a list of possible completions when I hit the TAB key:
我正在用 python 编写一个像程序一样的跨平台 shell，我想添加自定义选项卡完成操作。在 Unix 系统上，我可以使用内置的 readline 模块并使用如下代码来指定当我按下 TAB 键时可能的补全列表：
import readline
readline.parse_and_bind( 'tab: complete' )
readline.set_completer( ... )
How can I do this on Windows? I'd like to avoid relying on 3rd-party packages if possible. If no solution exists is it possible to simply trap TAB key press so that I can implement my own from scratch?
如何在 Windows 上执行此操作？如果可能，我想避免依赖第 3 方软件包。如果不存在解决方案，是否可以简单地捕获 TAB 按键，以便我可以从头开始实现自己的解决方案？

Do u have a look at PyReadline: a ctypes-based readline for Windows? Although 3rd-party packages is NOT your option, maybe it's useful for build one's own, isn't it:).
你看看PyReadline: a ctypes-based readline for Windows吗？虽然 3rd-party 软件包不是您的选择，但也许它对构建自己的软件包很有用，不是吗:)。
