Simple Python Turtle Graphic and Code: Esoteric Sun
An image of sun made mystical by the paisleys around the center. The simple and structured Python Turtle code below defines the procedure for drawing the paisleys.
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/basicpy...
