Então usamos uma importação relativa com `..` para as dependências:

```Python hl_lines="3" title="app/routers/items.py"
{!../../docs_src/bigger_applications/app/routers/items.py!}
```

#### Como funcionam as importações relativas

/// tip | Dica

Se você sabe perfeitamente como funcionam as importações, continue para a próxima seção abaixo.

Daher verwenden wir einen relativen Import mit `..` für die Abhängigkeiten:

```Python hl_lines="3" title="app/routers/items.py"
{!../../docs_src/bigger_applications/app/routers/items.py!}
```

Here `tokenUrl="token"` refers to a relative URL `token` that we haven't created yet. As it's a relative URL, it's equivalent to `./token`.
