Und in Python 3.10 und darüber macht:

```Python
q: str | None = Query(default=None)
```

... den Parameter optional, mit dem Defaultwert `None`, genauso wie:

```Python
q: str | None = None
```

Nur, dass die `Query`-Versionen den Parameter explizit als Query-Parameter deklarieren.

Bedenken Sie, dass:

```Python

```

oder:

/// note

Before FastAPI 0.108.0, Starlette 0.29.0, the `name` was the first parameter.

Also, before that, in previous versions, the `request` object was passed as part of the key-value pairs in the context for Jinja2.

  - Bucket Tags
  - Bucket Object-Lock configurations (including retention and legal hold configuration)
  - Bucket Encryption configuration

> NOTE: Bucket versioning is automatically enabled for all new and existing buckets on all replicated sites.

The following Bucket features will **not be replicated**, is designed to differ between sites:

- Bucket notification configuration
- Bucket lifecycle (ILM) configuration

```Python

//// tab | Python 3.8+

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

Тепер ми загорнемо її у `Annotated`, і отримаємо:

//// tab | Python 3.10+

```Python
q: Annotated[str | None] = None
```

////

//// tab | Python 3.8+

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

   * <p>Note that overflowing a {@code BloomFilter} with significantly more elements than specified,

In most setups this will keep the scanner slow enough to not impact overall system performance. Setting the `delay` key to a *lower* value will make the scanner faster and setting it to 0 will make the scanner run at full speed (not recommended in production). Setting it to a higher value will make the scanner slower, consuming less resources with the trade off of not collecting metrics for operations like healing and disk usage as fast.

## Em Detalhes

O marcador `@pytest.mark.anyio` informa ao pytest que esta função de teste deve ser invocada de maneira assíncrona:

{* ../../docs_src/async_tests/test_main.py hl[7] *}

/// tip | Dica

Note que a função de teste é `async def` agora, no lugar de apenas `def` como quando estávamos utilizando o `TestClient` anteriormente.
