Python 3D Graphics Tutorial 21: Understanding and Using Widgets in Vpython

In this video Lesson, we show how to interact with a Python model using widgets. We show how Vpython allows use of dropdown menus, radio buttons, check boxes and slider bars.

By incorporating widgets we can allow non-programmers to effectively interact with a model.
