### Incluir o `APIRouter`s para `usuários` e `itens`

Agora, vamos incluir os `roteadores` dos submódulos `usuários` e `itens`:

```Python hl_lines="10-11" title="app/main.py"

```

/// info | Informação

`users.router` contém o `APIRouter` dentro do arquivo `app/routers/users.py`.

### Die `APIRouter` für `users` und `items` inkludieren

Inkludieren wir nun die `router` aus diesen Submodulen `users` und `items`:

```Python hl_lines="10-11" title="app/main.py"
{!../../docs_src/bigger_applications/app/main.py!}
```

/// info

`users.router` enthält den `APIRouter` in der Datei `app/routers/users.py`.

```

### Подключение маршрутизаторов (`APIRouter`) для `users` и для `items`

Давайте подключим маршрутизаторы (`router`) из суб-модулей `users` и `items`:

```Python hl_lines="10-11" title="app/main.py"
{!../../docs_src/bigger_applications/app/main.py!}
```

/// info | Примечание

`users.router` содержит `APIRouter` из файла `app/routers/users.py`.

        fileBuilder.append(".tmp")
        dirtyFiles += directory / fileBuilder.toString()
        fileBuilder.setLength(truncateTo)
      }
    }

    /** Set lengths using decimal numbers like "10123". */
    @Throws(IOException::class)
    internal fun setLengths(strings: List<String>) {
      if (strings.size != valueCount) {
        invalidLengths(strings)
      }
