In what way? On my devices I have full access to the native APIs and robust networking libraries for access to web services. There's Git integration available. I'm not aware of any Android programming environments that provide on-device GUI builders. I can sync code using iCloud or Dropbox if Git is too heavyweight.

Frankly the options on Android look extremely primitive in comparison, and largely depend on off-device development for anything above very basic and incomplete terminal prompt level features. iOS on-device development went beyond that with commercial-grade on-device development environments a decade ago, but Android seems stuck there permanently.

I'm not really sure why that is, there doesn't seem to be any technical limitation preventing the emergence of well specified complete development environments, like Codea, Pythonista and Pyto on Android but it never seems to happen. When I got my first iPad I was half expecting to have to get an Android device eventually just to be able to code on it, but it never happened and the on-device development story on iOS has gone from strength to strength.

In a way that Python is provided by the system out-of-box, you can use regular PyGObject bindings for everything (or Pyside or whatever else you want), use any third party modules from system repos or pip - exactly how you would on a desktop; you can even use it to write system daemons. Neither iOS or Android can compete with that.
