This is a nice cross platform python framework which works for Android, Win7, Linux, Mac. iOS is possibile but very trivial as Apple doesn't allow scripting.

For iOS Python development would be to embed a Python interpreter into you app and distribute your Python script with it (so to play nicely with Apple rules). In this case your Python application would be a Python interpreter which is packaged with your script and runs it automatically. As I've said - it ain't pretty
