All samples are listed here. Old DirectPython had many samples (over 30) and modifying them all for this version would be too time consuming. However, I will at least try to cover some basic cases. The main principles are still the same so you can still learn a thing or two by examining those old samples.
The first tutorials shows how to initialize DirectPython and present a black window.
See Tutorial 1.
See the Samples-folder in the installation directory or run the DirectPython Sample Browser.
