You can code in Python right on this page! Simply click "Run" to see what the "turtles" can do. Then delete the default code in the window on the left and enter some Python code of your own. Click "Run" and the output will appear in the window on the right. Try some examples from my book Hacking Math Class Using Python or from the official Python turtle documentation.

In 3D!

Here's another Trinket you can play with in Python to change around a 3D Spirograph! And the graphics window is interactive, just like in Visual Python: right-click and mouse around to rotate the scene and double click and mouse around to zoom!
