* Es gibt auch eine Datei `app/dependencies.py`, genau wie `app/main.py` ist sie ein „Modul“: `app.dependencies`.
* Es gibt ein Unterverzeichnis `app/routers/` mit einer weiteren Datei `__init__.py`, es handelt sich also um ein „Python-Subpackage“: `app.routers`.
* Die Datei `app/routers/items.py` befindet sich in einem Package, `app/routers/`, also ist sie ein Submodul: `app.routers.items`.

* Он также содержит файл `app/dependencies.py`, который также, как и `app/main.py`, является модулем: `app.dependencies`.
* Здесь также находится подкаталог `app/routers/`, содержащий `__init__.py`.  Он является суб-пакетом: `app.routers`.
* Файл `app/routers/items.py` находится внутри пакета `app/routers/`. Таким образом, он является суб-модулем: `app.routers.items`.
