The other day I came across a Python implementation called Jython.
With Jython you can write Java applications with Python and compile them to pure Java.  
I was wondering: Android programming is done with Java.
So, is it possible to make Android apps with Jython?
sadly No.
Mobile phones only have Java ME (Micro Edition) but Jython requires Java SE (Standard Edition). There is no Jython port to ME, and there is not enough interest to make it worth the effort.
