A time ago I decided to learn Python and SAGE mathematics package (an open-source math tool), which is programmed in Python. So the below links are not “pure” Python, but Python mingled with SAGE.

- An animated construction of a Sierpinski Triangle (see this link for more on Sierpinski Triangles; I also posted the code as a text file here). A version lives on the web page of the English electronic music band Minimal States — click on the image to loop back to this site.
- Animated construction of a hypotrochoid, source code lives at this link. SAGE has one of my animated hypotrochoids on their “feature tour” here.
- An animated construction of an ellipse(see this link for more on ellipses). Original source code lives here. — nearly the same as the hypotrochoid.
- An epicycloid, source code at this link — near the same as the hypotrochoid.
- A sliding derivative line, source code lives at image site and this link. Step-daughter Katie tells me her calculus teacher used it in class. Similar, made the animated illustration of an inflection point here, similar code at image site and here.
- An animated illustration of Thale's Theorem, source code lives at image site and here.
- An animated illustration of the Butterfly Curve, source code lives at image site and here.
- A countour plot (see this link for more on countour plots).
- An animated graph.
- A spline curve used for interpolation.
- Graph of three-dimensional function.
- Graph of cubic polynomial.
- 3-D Icosahedron.
