Some of you may have encountered the Logo programming language or one of its many offshoots. A memorable aspect of Logo was its use of turtle graphics — a form of vector graphics similar to pen plotters. Notably, turtle graphics features a relative drawing cursor.
Standard Python includes a turtle graphics module. It doesn’t have a huge production value (there’s no easy way to save an image, for instance), but it can be fun to play with.

I’ve never been particularly interested in puzzle games. Figuring out software has filled that niche for me (plenty puzzling enough). So, I’ve never done a Sudoku puzzle. Recently I read a post about Tredoku, which is a kind of three-dimensional Sudoku.
In that post was an unsolved Tredoku puzzle. I wasn’t tempted to try to solve it myself, but I did think it might be fun to see if I could write some Python to do it.

The famous Fibonacci sequence starts off [1, 1, 2, 3, 5, 8, 13, 21, …] and continues forever. Each number in the series, except the first two, is the sum of the previous two numbers. For example, 3+5=8.
The canonical algorithm to calculate the series uses recursion and is elegant enough to be a common example of a recursive function. But while elegant conceptually, the algorithm is deadly computationally. In this post I’ll look at several ways to dodge the bullet.
