   * Past underutilization could mean that excess resources are available. Then, the RateLimiter

     * until we send the frame that acknowledges this new size.

そのため、（できれば）次のようにします:

```Python
q: Annotated[str, Query()] = "rick"
```

...または、古いコードベースでは次のようなものが見つかるでしょう:

```Python
q: str = Query(default="rick")
```

### `Annotated` の利点 { #advantages-of-annotated }

関数パラメータのデフォルト値スタイルではなく、**`Annotated` を使うことが推奨** されます。複数の理由で **より良い** からです。 🤓

**関数パラメータ** の **デフォルト値** は **実際のデフォルト値** であり、Python 全般としてより直感的です。 😌

Ele exige configurações um pouco mais verbosas. E como é baseado em WSGI (em vez de ASGI), ele não é projetado para tirar vantagem da alta performance fornecida por ferramentas como Uvicorn, Starlette e Sanic.

### Concorrência + Paralelismo: Web + Aprendizado de Máquina { #concurrency-parallelism-web-machine-learning }

Com **FastAPI** você pode levar a vantagem da concorrência que é muito comum para desenvolvimento web (o mesmo atrativo de NodeJS).

It requires a little bit more verbose configurations. And as it is based on WSGI (instead of ASGI), it is not designed to take advantage of the high performance provided by tools like Uvicorn, Starlette and Sanic.
