Você faz com tipos padrão do Python moderno.

Você não terá que aprender uma nova sintaxe, métodos ou classes de uma biblioteca específica etc.

Apenas **Python** padrão.

Por exemplo, para um `int`:

```Python
item_id: int
```

ou para um modelo mais complexo, `Item`:

```Python
item: Item
```

=====================

OkHttp 4.x upgrades our implementation language from Java to Kotlin and keeps everything else the
same. We’ve chosen Kotlin because it gives us powerful new capabilities while integrating closely
with Java.

We spent a lot of time and energy on retaining strict compatibility with OkHttp 3.x. We’re even
keeping the package name the same: `okhttp3`!

There are three kinds of compatibility we’re tracking:

    "price": 42.0,
    "tax": 3.2,
    "tags": ["rock", "metal", "bar"],
    "image": {
        "url": "http://example.com/baz.jpg",
        "name": "The Foo live"
    }
}
```

Novamente, apenas fazendo essa declaração, com o **FastAPI**, você ganha:

* Suporte do editor de texto (compleção, etc), inclusive para modelos aninhados
* Conversão de dados
* Validação de dados
* Documentação automatica

   * complete chunk are handled with {@link #processRemaining}.
   */
  protected abstract HashCode makeHash();

  // Process pent-up data in chunks
  private void munchIfFull() {
    if (buffer.remaining() < 8) {
      // buffer is full; not enough room for a primitive. We have at least one full chunk.
      munch();
    }
  }

/// note | Detalhes Técnicos

Você também poderia utilizar `from starlette.responses import HTMLResponse`.

O **FastAPI** fornece as mesmas `starlette.responses` como `fastapi.responses` apenas como um facilitador para você, desenvolvedor. Mas a maior parte das respostas vem diretamente do Starlette.
