summary
Builds modules and packages from scratch and demonstrates a working bookstore app split into modules for books authors users plus routes services and tests, shows how imports resolve via sys.path and PYTHONPATH, explains temporary vs permanent env changes (zshrc example), highlights need for an __init__.py to mark packages, measures benefits by independent testability and reduced blast radius when one module fails, and shows imports and selective from-import usage with concrete file examples.
