Simple Python Turtle Graphic and Code: Overlapping Squares смотреть онлайн

A group of squares made more visually appealing by the gradual decrease in size and change in hue of every shape that overlaps the preceding one. The simple Python Turtle code uses the colormode(1.0) to facilitate transition from initial color to terminal one. The code allows the user to alter the initial and terminal colors.

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
