Simple Python Turtle Graphic and Code: Power Symbol
One of the current variants of the power on/off symbols. incorporating both the I and O. The Python Turtle algorithm here utilizes color filled circles and rectangles to hide portions not needed for the final image.
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 more graphics and variations, please visit my author url at https://www.amazon.com/author/basicpy...
