Así que, querrás tener un **único proceso** para realizar esos **pasos previos**, antes de iniciar la aplicación.

#### <abbr title="Union – Verbund, Einheit‚ Vereinigung: Eines von Mehreren">Union</abbr>

Sie können deklarieren, dass eine Variable einer von **verschiedenen Typen** sein kann, zum Beispiel ein `int` oder ein `str`.

In Python 3.6 und höher (inklusive Python 3.10) können Sie den `Union`-Typ von `typing` verwenden und die möglichen Typen innerhalb der eckigen Klammern auflisten.

## Ejemplo

### Créalo

* Crea un archivo `main.py` con:

```Python
from typing import Union

from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")
def read_item(item_id: int, q: Union[str, None] = None):
    return {"item_id": item_id, "q": q}
```
