I was following the Wordle craze, looking for a list of five-letter words. Little did I know I'd stumble upon the Stanford GraphBase. https://github.com/4dsolutions/elite_school/blob/master/ADS_research_1.ipynb There's also some Pi Day stuff, for teachers taking advantage of 3-14. Kirby ==== Exhibit from March 2022: Hi Guys -- Our topics today included: * arbitrary precision numbers as provided by decimal.Decimal or gmpy2 * algorithms for converging to Pi (one of Ramanujan's and one I learned from Guido) * another rear view mirror look at Five Letter Land * SymPy https://mpmath.org/ Friendly Repo: https://nbviewer.org/github/4dsolutions/Python5/blob/master/Pi%20Day%20Fun.i... Friendly Replit: https://replit.com/@kurner/piday#main.py In fact we were indeed discovering some of the same Graph Theory facts about the list of five letter words, that come to light in the Stanford GraphBase course, authored by Knuth himself (Chinese name "Gartner"): https://blog.krybot.com/a?ID=0 1800-af2c69d8-40ba-4b02-9cdc-aca2c205be68 <https://blog.krybot.com/a?ID=01800-af2c69d8-40ba-4b02-9cdc-aca2c205be68> https://replit.com/@kurner/fiveland#main.py I finally got that Regular Expressions sandbox to work: https://regex101.com/r/k0eF6r/1 I felt it important to bring up the topic of Regular Expressions because they're used in many algorithms where the task is to do pattern matching. See you Monday. Keep thinking about those projects. Mandelbrots and Mandelbulbs: another topic we touched upon.
