Editorial interest 83/100 Selection signal · not a rating of the site

A visual-learning project that teaches Python, NumPy and Pygame through image experiments, game labs and a planned book.

Landing page captured for the 2026-10-31 issue.
For
Python learners who learn by visual experimentation
Worth noticing
The slicing demo is an interactive JavaScript model; the page explicitly says it does not execute Python.

Field notes

The slicing exercise uses image[2:6, 2:6] to show how row and column ranges select 16 cells, with an explanation of the excluded stop index. Its visible interaction is a JavaScript model rather than Python execution. The linked labs map matrix concepts onto game scenarios, while the planned three-volume book is marked as still in preparation.
