I've just putting the finishing touches on several small projects that are centered around Jython and several widely available java libraries. I chose Jython for several reasons.
Python just fits how my brain works. Weird I know, but that is my reality.
But not everyone has Python installed, or has the right release of python.
So I write my software in python that I can compile into a java jar using Jython and thus piggy back on the general availability of the Java platform!
