Python has been implemented in several different ways; the standard interpreter in C (CPython), in python itself (PyPy), in the .Net Dynamic Language Runtime (C#) (IronPython), and in Java on the Java Virtual Machine (Jython). Jython comes with java interoperability; allowing it to leverage powerful java libraries, such as Libgdx, while keeping the succinctness and readability of Python.

Note: at the time of writting, you can only use Jython with libGDX on the desktop.

The entirety of the can be contained into a single python file.
