Simple Python Turtle Graphic and Code: Multiple Fans
Multi Fans uses the geometric fact that a hexagon is surrounded snugly by six similarly sized ones. The image also utilizes the Python feature that allows an S form starting from a tip of a line and ending on the other to create 2 color-filled regions when "fillcolor" is used
Feel free to copy the basic Python Turtle code that is given below. Don't hesitate to write comments or ask questions about the code if you have any. Enjoy! Please comment, like, or subscribe :)
