Simple Python Turtle Graphic and Code: Parallel Planes смотреть онлайн

A group of stacked parallelograms created by the "goto" method. To make the simple graphic more interesting, step-wise change in color of parallelograms was made using the screen.colormode(1.0) and the conventional formulas for change in r, g, and b were utilized in the short code.

Feel free to copy the basic Python Turtle code that is given below. Don't hesitate to ask questions about the code if you have any. Enjoy! Please comment, like, or subscribe :)

Incidentally, for manually colorable graphics and variations, please visit my author site at https://www.amazon.com/author/basicpythonturtleart.url
