Day 79 · Week 12
Week 12 · Build our next increment
Scheduled session · Tuesday, 1 December 2026

Our planned session
We practise strings, lists, dictionaries, and type hints by improving that function.
Weekly outcome
A tested Python text utility we can explain from TypeScript knowledge.
Readiness check
We build on Week 11: The existing companion runs reproducibly in a local service stack. If its required checks remain incomplete, we use this week to finish or reduce scope first.
Human approval gate
We run the utility and tests and explain its input, output, and error behaviour.
