I found this application on the app store: iLuaBox and I wondered if there was anything else like this for the iPhone without jailbreaking but instead for Python or Ruby?
Lua is probably similar for me to play around with the basic programming I do anyway but I thought I would just ask)
A python interpreter App called Python for iOS is available on the App store:

Full disclosure: I am the sole creator/developer of the Python for iOS App.
