Hier sind einige zusätzliche Ideen, die beim Arbeiten mit Python-Typen nützlich sein könnten.

## `Union` oder `Optional` verwenden { #using-union-or-optional }

Wenn Ihr Code aus irgendeinem Grund nicht `|` verwenden kann, z. B. wenn es nicht in einer Typannotation ist, sondern in etwas wie `response_model=`, können Sie anstelle des senkrechten Strichs (`|`) `Union` aus `typing` verwenden.

## Utiliser `Union` ou `Optional` { #using-union-or-optional }

Si votre code ne peut pas utiliser `|` pour une raison quelconque, par exemple si ce n'est pas dans une annotation de type mais dans quelque chose comme `response_model=`, au lieu d'utiliser la barre verticale (`|`) vous pouvez utiliser `Union` de `typing`.

## `Union` o `anyOf` { #union-or-anyof }

Puedes declarar un response que sea la `Union` de dos o más tipos, eso significa que el response sería cualquiera de ellos.

Se definirá en OpenAPI con `anyOf`.

Para hacerlo, usa la anotación de tipos estándar de Python [`typing.Union`](https://docs.python.org/3/library/typing.html#typing.Union):

### `Union` en Python 3.10 { #union-in-python-3-10 }

Python tipleriyle çalışırken işinize yarayabilecek bazı ek fikirler.

## `Union` veya `Optional` Kullanımı { #using-union-or-optional }

Kodunuz herhangi bir nedenle `|` kullanamıyorsa — örneğin bir tip açıklamasında (type annotation) değil de `response_model=` gibi bir yerdeyse — dikey çizgi (`|`) yerine `typing` içindeki `Union`'ı kullanabilirsiniz.

Örneğin, bir şeyin `str` ya da `None` olabileceğini şöyle belirtebilirsiniz:

## Usando `Union` ou `Optional` { #using-union-or-optional }

Se, por algum motivo, seu código não puder usar `|`, por exemplo, se não for em uma anotação de tipo, mas em algo como `response_model=`, em vez de usar a barra vertical (`|`) você pode usar `Union` do `typing`.

Por exemplo, você poderia declarar que algo pode ser `str` ou `None`:

```python
from typing import Union


def say_hi(name: Union[str, None]):

## `Union` 或 `anyOf` { #union-or-anyof }

响应可以声明为两个或多个类型的 `Union`，即该响应可以是这些类型中的任意一种。

在 OpenAPI 中会用 `anyOf` 表示。

为此，请使用 Python 标准类型提示 [`typing.Union`](https://docs.python.org/3/library/typing.html#typing.Union)：
