Any better alternatives? > Depending on how much user input is needed in your application, you can always use the 'cmd' module: http://docs.python.org/library/cmd.html It is present in both Python 2 and Python 3 and should just 'do the right thing'. It also seamlessly integrates readline (if present), command-completion, and provides a built-in help menu for defined commands. It's written in pure Python, and in my opinion, the best form of documentation for that module is the source code itself. I haven't used it in Python 3, but I imagine it can be used in a way that easily supports Python 2 and 3. If you have only one or two places where you need user-input, this is probably overkill.
