### 🔌 `APIRouter`Ⓜ `users` & `items`

🔜, ➡️ 🔌 `router`Ⓜ ⚪️➡️ 🔁 `users` & `items`:

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

/// info

`users.router` 🔌 `APIRouter` 🔘 📁 `app/routers/users.py`.

    if (-2 <= b && b <= 2) {
      switch ((int) b) {

### Include the `APIRouter`s for `users` and `items`

Now, let's include the `router`s from the submodules `users` and `items`:

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

/// info

`users.router` contains the `APIRouter` inside of the file `app/routers/users.py`.

{!../../docs_src/bigger_applications/app/main.py!}
```

### 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"
{!../../docs_src/bigger_applications/app/main.py!}
```

/// info | "Informação"

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

{!../../docs_src/bigger_applications/app/main.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`.
