Learn Python TDD Style with Python Koans

on YouTube ↗01h 25m

" summary

Hands-on workshop that teaches Python by fixing a suite of deliberately broken tests converted from Ruby Koans; run contemplate_koans.py from either the Python 2 or Python 3 folder, edit files to replace __ placeholders, and iterate with the built‑in unit test runner until green. Repo is on GitHub so you can git clone or download a zip; exercises include triangle classification, stacks/queues, generators and exception‑message matching, with small red→green refactor cycles.
