This glossary belongs to Module 02: Design Roles, Interfaces, and Layering in Python Object-Oriented Programming. It keeps the language of this directory stable so the same ideas keep the same names across reading, practice, review, and capstone proof.

How to use this glossary

Read the directory index first, then return here whenever a page, command, or review discussion starts to feel more vague than the course intends. The goal is stable language, not extra theory.
