Welcome to Python 4000, or the intermediate lessons designed to help us understand how we can use Python's Turtle Graphics subsystem to create professional simulations, as well as models, that we can re-use to manage our ideas in the classical 2D, as well as 3D, modeling worlds.

The second part of a three-part lesson set, in Python 4000 students will be building upon their Python 3 programming experience.

In this Python 4000 training opportunity, we will move past our basic understandings of motion-based shapes and mathematical planes so as to allow us to create graphical frameworks -Design patterns that will allow us to call our functions within Python's classical Cartesian graphics plane. Along the way we will also discover how to graphically gather input from application users, as well.

If you're not familiar with how to create and use frameworks, or have never used a callback function, then I think you will find our intermediate training - or Python 4000 for Turtle Graphics - to be something that you don't want to miss. --Certainly a lesson set that you'll want to re-use, as well as practice, several times!

In addition to covering Pythons Cartesian graphics support, the clandestine objective in the lesson set is to allow students to get used to using graphical frameworks: Models that can call-back our own member functions whether they're stand alone, lambdas, in a class, or deliberately destined to support those whom will be re-using our modeling, and simulation, efforts.
