Can I write native iPhone, Android, Windows, Blackberry apps using Python? [duplicate]

Yes you can use kivy

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.

And for Android Google provides something called ASE (Android Scripting Environment) which allows scripting languages (Python included) to run on Android. More details here

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 prettyYou can check details Here

Hope it helps you.

Not out of the box. The final product needs to be compiled (iOS) or in bytecode (Android). Since it may be possible to convert Python code to Objective-C or something in between it might be possible.

See Kivy — the previous thread referenced it. This allows you to write you app in Python but probably uses a common wrapper (that Kivy provides) to run Python.

Please note that code written in Objective-C (iOS) or Java (Android) will always be faster than middle-ware like Kivy or Phonegap. Unless the one developing is very bad at writing any of those native languages....
