Simple Python Turtle Graphic and Code: Wire Mesh
Wires woven into a mesh. The visible wires are represented by rectangles that are color-filled to show overlaps at intersections. The basic Python Turtle code here, although a bit long at 50 plus lines, can still be shortened perhaps by using tuples and embedded loops.
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 :)
