Python：通过让用户编辑默认值来获取用户输入

Question

I've got a script that pulls text from a Web server. I want to give the user (me) an opportunity to edit that text so they can select which part to keep. Ideally, it would be something like this:

editedText= raw_input(defaultText)

So, defaultText is printed, the user edits it and presses enter, and the text as they've edited is assigned to editedText .

Is there a way to do this?
Thanks!

Yes, there is a way. Use readline

import readline

defaultText = 'I am the default value'
readline.set_startup_hook(lambda: readline.insert_text(defaultText))
res = raw_input('Edit this:')
print res

Note that this is not a terribly portable solution, and I've only tested it on Linux :)
