...E declare o tipo como o modelo que você criou, `Item`.

## Resultados

Apenas com esse declaração de tipos do Python, o **FastAPI** irá:

* Ler o corpo da requisição como um JSON.
* Converter os tipos correspondentes (se necessário).
* Validar os dados.
    * Se algum dados for inválido, irá retornar um erro bem claro, indicando exatamente onde e o que está incorreto.

      NetworkInterface i = interfaces.nextElement();
      builder.add(i.getName()).add(String.valueOf(i.getIndex()));
    }
    return builder.build();
  }

  /** Checks that the IP converts to the big integer and the big integer converts to the IP. */
  private static void checkBigIntegerConversion(String ip, BigInteger bigIntegerIp) {
    InetAddress address = InetAddresses.forString(ip);

```

Het aanroepen van dit programma leidt tot het volgende resultaat:

```
John Doe
```

De functie voert het volgende uit:

* Neem een `first_name` en een `last_name`
* Converteer de eerste letter van elk naar een hoofdletter met `title()`.
``
* <abbr title="Voegt ze samen, als één. Met de inhoud van de een na de ander.">Voeg samen</abbr> met een spatie in het midden.

```Python hl_lines="2"

E a parte posterior do `yield` irá executar **após** a aplicação ser encerrada.

### Gerenciador de Contexto Assíncrono

Se você verificar, a função está decorada com um `@asynccontextmanager`.

Que converte a função em algo chamado de "**Gerenciador de Contexto Assíncrono**".

```Python hl_lines="1  13"

```

TensorFlow supports a wide range of input data formats. For example it can
process images, audio, videos, and text. There are several modules specialized
in taking those formats, modifying them, and/or converting them to intermediate
formats that can be processed by TensorFlow.

These modifications and conversions are handled by a variety of libraries that
have different security properties and provide different levels of confidence

Vous pouvez aussi retourner des models **Pydantic** (qui seront détaillés plus tard).

Il y a de nombreux autres objets et modèles qui seront automatiquement convertis en JSON. Essayez d'utiliser vos favoris, il est fort probable qu'ils soient déjà supportés.

## Récapitulatif

* Importez `FastAPI`.
* Créez une instance d'`app`.
