a simple UI for python learners
by Kent Tong 22 Sep '21

22 Sep '21

Hi, I have written a small Python package (https://pypi.org/project/lineui/) to provide an API to a one-line user interface (like that in a calculator) for Python learners.It provides the following features: - output in the line (left, right or middle aligned). - output in the console (the lower box), mainly for debugging. - keyboard input. - timer input (every second or every 0.05 seconds). - schedule a call to a function a certain seconds later. - make a beep.With these a Python learner can make apps like: digital clock, the classic digit invaders game, slapjack, etc. -- Kent Tong IT author and consultant, child education coach

git-based tutorial system
by Jurgis Pralgauskis 07 Sep '21

Hi, I want to have "record" and "playback" tool for coding tutorials. Git seems quite suitable as DB for such case. Maybe you know such tools? ps.: commit messages would hold explanations -- that can be read TTS to have voice in tutorial :) pps.: or commits could be very granular (example, on each word/token change) then tag annotations would hold the explanations -- Jurgis Pralgauskis tel: 8-616 77613; Don't worry, be happy and make things better ;) https://galvosukykla.wordpress.com/

update on Pythonic High School curriculum writing
by kirby urner 20 Aug '21

20 Aug '21

Here's an updated link to my open source curriculum writing. https://nbviewer.jupyter.org/github/4dsolutions/elite_school/blob/master/Ho… Pythonic High School Math one might call it, with bridges to other STEAM topics, and thence to PATH. [1] I introduce folks to my Notebooks using nbviewer because the native Github rendering is less thorough i.e. LaTeX is not interpreted. LaTeX, Git, SQL... all important high school topics. Kirby [1] I'm not sure how much PATH caught on after Andrew Hacker used it in The Math Myth. An attempt to map the Humanities with four letters, copying the STEM idea (Science Technology Engineering Mathematics for those of you not using this namespace). I've customized PATH to mean Philosophy Anthropology Theater History, with Theater having an expanded meaning ("all the world is a stage"). Then the local custom is to expand STEM to STEAM saying A is for Art and claiming here's a way to bridge the CP Snow Chasm twixt the Sciences and the Humanities. My wrinkle is to use A for Anthropology (which includes Art in my account) and to intersect on this Science-Humanities topic (the study of we humans and our many subcultures i.e. cults).

py -> UML (reverse engineering)
by Jurgis Pralgauskis 07 Jul '21

Hi, I mostly used Pycharm pro Class diagram, but it does not provide Composition/Association links... looking around, I find: - pyreverse - most simple (in pylint or sphinx <https://github.com/alendit/sphinx-pyreverse>) (demo <https://web.archive.org/web/20151121004322/https://www.logilab.org/blogentr…>, demo <https://charlesreid1.com/wiki/Pyreverse>) -- seems, no composition links - https://pypi.org/project/py2puml/ - https://github.com/abulka/pynsource - seems most robust (round-trip) seems by same author: https://www.gituml.com/fiddle/python/ https://github.com/abulka/lcodemaps (bit off-topic, but looks interesting) Maybe smb knows/tried more? -- Jurgis Pralgauskis tel: 8-616 77613; Don't worry, be happy and make things better ;) https://galvosukykla.wordpress.com/

summer school enrichment course: advance high school topics in Python
by kirby urner 29 Jun '21

29 Jun '21

When I introduce OOP to high schoolers, I go straight to this word "object" and link it with the word "thing" in the ordinary sense of the word. Objects are not meant to be learned as an abstract computer science idea, but as an adaptation of ordinary language, trying to make reasoning about the real world expressible in a computer language. The challenge is not unlike the one faced by the logicians at the turn of the last century, looking for a "propositional calculus" but with the added notion of "executability" (the idea of a self-executing logic was there from the beginning, as appreciated by Ada vis-a-vis the Babbage Engine). Etymologically, a "thing" is actually a Scandanavian meetup of some kind i.e. a thing is a meeting of things, which is apropos of a recursive, fractal, "all the way down" subject such as particle zoo physics. So what are some paradigm "things" we can sink our teeth into (idiom): * Atoms (already current in high school -- I'm thinking to sync with whatever else they're learning) * Animals (everyone loves dogs and cats and taxonomy applied to "kingdoms" is a perennial trope in our science culture) * Polyhedra (probably my most controversial suggestion, but my bridge to geometry: figurate and polyhedral number sequences ala OEIS, coordinate systems, vector spaces... the rest of high school math. With Atoms I might just go with a namedtuple and circle back later with a corresponding @dataclass. With Animals I have the opportunity to subclass Animal into Dog, Cat and usually Snake classes. But start with Dog, evolve it, then move some of its functions to the parent Animal class (e.g. eat) when needing a Cat. With Polyhedrons I have V, F, E (topological features inventory) e.g. for subclass Cube that'd be 8, 6, 12. However Polyhedrons are complex objects, definable with radial vectors from a center and surface edges as vector pairs, with faces as rings (literally, cycles) of edges. This gets us into relational tables territory i.e. serves as our bridge to SQL.

following up on edu summit (pycon 2021)
by kirby urner 13 May '21

13 May '21

Greetings all. Good to see some of you at the Edu Summit. Many thank you to the organizers for allowing me to join in the end. Andre gave a fabulous talk on friendly, the enhanced, multi-lingual traceback explainer. My lightning talk came at the end. For those who couldn't be there, I'm fleshing it out a bit more on Youtube -- still in under 5 minutes. https://youtu.be/B9CvWok7SgU Lightning Talk (in connection with Edu Summit, Pycon 2021) We talked a lot about data science, wherein data visualization is key. Everyone wants to learn pandas. My own curriculum development efforts, informed by real experience teaching at these grade levels, focuses on a different kind of "graph", namely the polyhedrons (edges, nodes...) and 3D graphics more generally. That's another kind of visualization, as distinct from data visualization, that computers are in principle good at. We can get there with Python, with Blender perhaps, so another ray tracer solution.[1] However we still integrate well with data science and such, as such tabular structures as provided by pandas & SQL provide a logical way to store our polyhedrons. Relationally. With edges and vertices stored separately from the summary rows i.e. the actual polys by name ("cube"), with V, F, E (8, 6, 12), maybe relative volumes [2], and tags, like Platonic, Archimedean, Johnson, Uniform, Space-Filler, Dual of [ ] etc. etc. Kirby [1] e.g. check out Adrian's anti-prism which I've compiled for a Raspberry Pi. Not written in Python, but does output in .pov format for rendering, which is what a lot of my scripts also do. A great way to learn XYZ coordinates and more, no? http://www.antiprism.com/ [2] https://nbviewer.jupyter.org/github/4dsolutions/Python5/blob/master/Polyvol…

Looking forward to Pycon, although Education Summit is full
by kirby urner 04 May '21

04 May '21

I did a proposal for Pycon really early, then realized the Education Summit was separate. Now the latter is full and closed. I'm in the Trainers' Summit, but the Education Summit is full. Even to those of us who would just listen on Zoom? Oh well, good thing I turned my presentations in Youtube videos. I had a feeling I wouldn't actually get conference time. Here they are: https://youtu.be/rhrITxrRRyA https://youtu.be/hsGfcqhaPd8 I tend to always be focused on the same themes, where I imagine I have some competitive advantage maybe? Maybe I'll connect with some of you around the edges of said Education Summit, which I used to help plan in the early days. Kirby
