lesson plan idea (math with python, pandas...)

https://github.com/4dsolutions/clarusway_data_analysis/blob/main/Kirby%20No… Maybe I'm especially slow in finding out about a Magic Square, 128 by 128, that also works when its elements are 2nd powered, and works again when they're 3rd powered. OMG! As a worker bee on along the data science track, showing noobs the ropes re Python's ecosystem in the pandas numpy matplotlib seaborn department, I see the potential for relevant skills building. Find the Square in question (Tarry's) on the … [View More]

I think this link will work: https://www.flickr.com/photos/kirbyurner/54152008669/sizes/h/ Goes to a large enough view of my screen, showing Google Colab, a public facing free interface, wherein I've just prompted its Gemini code assistant (AI) to plot a purple Bell Curve. It writes and explains the code. I've cut and pasted it verbatim into a code cell on the left for execution. The output is shown. Pretty nifty if you ask me.

Pythonic Geometry
by kirby urner Oct. 9, 2024

Oct. 9, 2024

Long timers here might remember Arthur Siegel's PyGeo, still on Sourceforge <https://pygeo.sourceforge.net>. He and I used to endlessly debate, here on this edu-sig listserv, the relative advantages of this or that pythonic pedagogy, but were in agreement that VPython <https://vpython.org>, or Visual Python, was in the toolkit. We managed to meet up in New York City, then I had to abort a second meetup at a Pycon and yada yada... I only met him in person that one time. No Zoom yet. … [View More]

"indigs" as a topic for intro to python
by kirby urner Aug. 26, 2024

Aug. 26, 2024

I encourage Pythonistas into teaching Python in the context of generic computer science and mathematics, high school and above (and below for the precocious) to consider "indigs" an accessible example of recursion at work. I'm testing it out in a warm up section students might visit if feeling shaky on their Python, or just wanting more background reading. https://github.com/4dsolutions/clarusway_data_analysis/blob/main/python_war… The idea of an indig is very simple and inherits from … [View More]

Python teachers comparing notes...

To edu-sig: ---------- Forwarded message --------- From: Kirby Urner <kirby(a)clarusway.com> Date: Sun, Aug 18, 2024 at 7:32 AM Subject: Fwd: Side topic: IDEs To: kirby urner <kirby.urner(a)gmail.com> Feel free to write to me at Clarusway as well. Kirby ---------- Forwarded message --------- From: Kirby Urner <kirby(a)clarusway.com> Date: Wed, Jul 24, 2024 at 4:26 PM Subject: Side topic: IDEs To: Edwin W <edwin(a)clarusway.com>, kirby urner <kirby.urner(a)… [View More]gmail.com> Hi Edwin -- I thought we could have more than one thread going, branching off Incoming Cohort Planning (ongoing). I've seen and taken various approaches to the topic of Interactive Development Environments. Here are some talking points I've used: * you the developer have a choice from a huge variety of IDEs <https://www.creativebloq.com/advice/best-code-editors>, and they continue to evolve. * Don't be afraid to sample several. * Even when you have a favorite, you might want to keep dabbling with the competition, just to see what they're like * IDEs divide into two major categories: (a) IDEs that work with many computer languages, usually by means of "plug ins" (b) IDEs devoted to one primary language only (example: Spyder) Screenshot of me using Spyder just now (when I wanted to test that pi generator again): [image: Screen Shot 2024-07-24 at 4.18.08 PM.png] Sometimes I talk about the history, meaning the lineage, meaning some IDEs grew up inside Windows whereas others derive from a Linux/Unix/Mac background (vi vim emacs). If I'm sharing my screen, I can show some of these IDEs while I mention them, otherwise it can just be information embedded in some Notebook. I used IDLE for years, the IDE that comes with Python when you get it from Python.org. Anaconda gives you Spyder. One reason Python became very popular is because IDLE is cross platform, running in Windows, Mac, Linux pretty much the same way. Guido got a US government grant to work on IDLE (even though he's a Dutch citizen). When I worked for O'Reilly School of Technology, we had our students using remote (cloud based) versions of Eclipse, which was cutting edge but also a bit awkward. Eclipse <https://en.wikipedia.org/wiki/Eclipse_(software)> (open source project of IBM) features plug-in architecture and works with many languages, but was especially made for Java. I understand that the Clarusway Python courseware is Notebook based, which is not a problem, that's a good environment. I was just wondering if you think it's worthwhile to talk about IDEs, how they are different from Notebooks, and how a Python coder has a choice from many of them. I like how Spyder integrates features and have used it a lot when sharing from an IDE when teaching Python online. Kirby [View Less]

passing on Python lore
by kirby urner July 25, 2024

July 25, 2024

I'm herewith archiving an email from earlier today, to the guy in charge of the Python curriculum at this company I work for (see LinkedIn profile). It refers back to this listserv, in the context of recycling what I consider a choice piece of Python lore: that generator for deriving digits of pi. -- Kirby ---------- Forwarded message --------- From: Kirby Urner <kirby(a)clarusway.com> Date: Wed, Jul 24, 2024 at 4:05 PM Subject: Python generators (a fun example, not by me) To: On … [View More]the topic of Python generators, I just wanted to share what I consider a mysterious one, meaning I didn't write it and don't understand why it works (eyeballing the code has not yielded answers). It may have actually come to me from Guido himself if I remember how it went on edu-sig (one of the archived Python.org discussion groups on which I've been active). He and I have a long term shared interest around integrating Python into everyday math learning (we've come a long way since then). For context, I'm copying this Python generator from my Jupyter Notebook called Pi Day, which is about using Python to generate the number pi in various ways: https://nbviewer.org/github/4dsolutions/Python5/blob/master/Pi%20Day%20Fun.… Although most of the Python is by me, I'm simply implementing algorithms discovered by others (it's about their genius, not mine), such as that famous one by Ramanujan in the middle of the page. Here's the generator I'm talking about (at the very end of the above notebook, before the flashing GIF pizza pi): """ Another generator example: converging to Pi https://mail.python.org/pipermail/edu-sig/2015-September/date.html """ def pi(): k, a, b, a1, b1 = 2, 4, 1, 12, 4 while True: p, q, k = k*k, 2*k+1, k+1 a, b, a1, b1 = a1, b1, p*a+q*a1, p*b+q*b1 d, d1 = a/b, a1/b1 while d == d1: yield int(d) a, a1 = 10*(a%b), 10*(a1%b1) d, d1 = a/b, a1/b1 if __name__ == "__main__": the_gen = pi() for _ in range(100): print(next(the_gen),end="") print() If I run that I get (I also have 3.9 as well as 3.11): Python 3.9.12 (main, Apr 5 2022, 01:53:17) Type "copyright", "credits" or "license" for more information.

introducing python
by kirby urner April 18, 2024

April 18, 2024

When I start introducing Python I use this chart [1]: Five Dimensions of Python: - Level 0: core syntax with keywords & punctuation, indentation (import, if...) - Level 1: a large set of built-ins (e.g. print) - Level 2: special names with the double underlines - Level 3: Standard Library (e.g. math) - Level 4: 3rd Party Ecosystem (e.g. numpy, pandas, matplotlib) Here's a Level 2 topic I've been recently working on: https://nbviewer.org/github/4dsolutions/m4w/blob/… [View More]
