### Exceptions

Some legitimate exceptions exist where British English or other variants must be preserved:

* **Third-party APIs and libraries**: When integrating with external APIs that use different spelling conventions
* **Historical compatibility**: Existing public API methods that are part of Gradle's stable API cannot be renamed due to backward compatibility requirements (though new APIs should use American English)

```Python
q: Annotated[Union[str, None]] = None
```

Ambas as versões significam a mesma coisa, `q` é um parâmetro que pode ser `str` ou `None`, e por padrão é `None`.

Agora vamos pular para a parte divertida. 🎉

## Adicione `Query` ao `Annotated` no parâmetro `q` { #add-query-to-annotated-in-the-q-parameter }

Tam da bu yüzden **FastAPI** Starlette'e dayanıyor, çünkü Starlette şu anda kullanılabilir en hızlı framework. (üçüncü parti karşılaştırmalı testlerine göre)

In general, ASGI middlewares are classes that expect to receive an ASGI app as the first argument.

So, in the documentation for third-party ASGI middlewares they will probably tell you to do something like:

```Python
from unicorn import UnicornMiddleware

app = SomeASGIApp()

new_app = UnicornMiddleware(app, some_config="rainbow")
```

**FastAPI** tomará el modelo de Pydantic de allí, generará el JSON Schema y lo colocará en el lugar correcto.

É a partir dele que o FastAPI irá extrair os parâmetros passados e será o que o FastAPI irá realmente chamar.
