Simple Python Turtle Graphic and Code: Settings Symbol
The conventional symbol for settings created by concentric filled circles and curcumferencial rectangles.
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 :)
