Unfortunately Python 3.x includes a lot of incvompatible changes to the Python language so that version 2.x has still to be maintained, as a lot of solutions are based on this version | For historical reasons there are two versions of Python language avilable: Python 2.x and Python 3.x.

It allows Python code to interact with the CLR, and may also be used to embed Python into a .NET application. | ||

| An older version of VEGASPythion was based on IronPython. IronPython is an open source implementation of Python for .NET. The development had been started by Microsoft but is now given to an open community that is still active and provides regularly new updated versions of IRONPython. | An older version of VEGASPythion was based on IronPython.
