Forgive the density of this question, but.. what exactly can you do with this? There is very little info both on the app's page, as well as the author's webpage.
Can you, for instance, import os (or equivalent) and interact with the phone's file system? Does the standard lib work, or some percentage of it?
It gives you an interactive python shell on your iOS device. You can't access the file system, because of the OS's sandboxing rules. The standard library does work modulo any sandbox rules. You can, for example, write scripts that use urllib to talk over a network and do some work.
I keep seeing this on HN, and keep thinking "Finally, can write apps in python", then it goes back to the same old python shell program and I'm a bit saddened.
