## Overview

A small Flask product API: clients request collection or item operations, `app.py` handles routing and request/response behavior, and `db.py` performs product persistence through Peewee in SQLite. The README documents CRUD endpoints plus standalone database setup, default-data, and print operations; the sampled source confirms those database utilities. No separate validation or service layer is present.

Main entry points: [`db.py`](https://github.com/sashasanch3z/docker-compose-python/blob/main/db.py) (Product model), [`app.py`](https://github.com/sashasanch3z/docker-compose-python/blob/main/app.py) (Flask API)
