## `Union`または`anyOf`

レスポンスを２つの型の`Union`として宣言することができます。

OpenAPIでは`anyOf`で定義されます。

そのためには、標準的なPythonの型ヒント<a href="https://docs.python.org/3/library/typing.html#typing.Union" class="external-link" target="_blank">`typing.Union`</a>を使用します:

```Python
# Esto no funcionará, porque get_burgers se definió con: async def
hamburguesas = get_burgers (2)
```

---

Por lo tanto, si estás utilizando una library que te dice que puedes llamarla con `await`, debes crear las *path operation functions* que la usan con `async def`, como en:

```Python hl_lines="2-3"
@app.get('/burgers')
async def read_burgers():

        tf.Tensor` The `tf.ExtensionType` base class works similarly to
        [`typing.NamedTuple`](https://docs.python.org/3/library/typing.html#typing.NamedTuple)
        and
        [`@dataclasses.dataclass`](https://docs.python.org/3/library/dataclasses.html#dataclasses.dataclass)
        from the standard Python library.
    *   Extension types are supported by Keras, tf.data, TF-hub, SavedModel,

If you are planning to use digital signature algorithms like RSA or ECDSA, you should install the cryptography library dependency `pyjwt[crypto]`.

You can read more about it in the <a href="https://pyjwt.readthedocs.io/en/latest/installation.html" class="external-link" target="_blank">PyJWT Installation docs</a>.
