The first question that comes to mind is why one would want do to something like this. Although Python is interpreted it is compiled to java bytecode.
Performance is on par with native java code.
Python is very easy to learn. This, together with the fact that you don't need to use a compiler, makes it possible for people with little java experience to create screens. This will create a new turbine library that contains the Python code. You need to copy this new .jar file to your application's lib directory. Now we need to edit the TurbineResources.properties.
