Show default value for editing on Python input possible?

Question

Is it possible for python to accept input like this:

 Folder name: Download 

But instead of the user typing "Download" it is already there as a initial value. If the user wants to edit it as "Downloads" all he has to do is add a 's' and press enter.

Using normal input command:

folder=input('Folder name: ') 

all I can get is a blank prompt:

 Folder name: 

Is there a simple way to do this that I'm missing?

The standard library functions input() and raw_input() don't have this functionality. If you're using Linux you can use the readline module to define an input function that uses a prefill value and advanced line editing:

import readline  def rlinput(prompt, prefill=''):    readline.set_startup_hook(lambda: readline.insert_text(prefill))    try:       return input(prompt)  # or raw_input in Python 2    finally:       readline.set_startup_hook()
