* There's a subdirectory `app/routers/` with another file `__init__.py`, so it's a "Python subpackage": `app.routers`.
* The file `app/routers/items.py` is inside a package, `app/routers/`, so, it's a submodule: `app.routers.items`.
* The same with `app/routers/users.py`, it's another submodule: `app.routers.users`.

* 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`.
* Das Gleiche gilt für `app/routers/users.py`, es ist ein weiteres Submodul: `app.routers.users`.

/// tip | Tipp

Beachten Sie, dass Sie nicht den Router selbst (`invoices_callback_router`) an `callback=` übergeben, sondern das Attribut `.routes`, wie in `invoices_callback_router.routes`.

### Es in der Dokumentation testen { #check-the-docs }

* 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`.
* Точно также `app/routers/users.py` является ещё одним суб-модулем: `app.routers.users`.
