```Python
    first_name="john", last_name="doe"
```

Es algo diferente.

Estamos usando los dos puntos (`:`), no un símbolo de igual (`=`).

Añadir los type hints normalmente no cambia lo que sucedería si ellos no estuviesen presentes.

Pero ahora imagina que nuevamente estás creando la función, pero con los type hints.

En el mismo punto intentas iniciar el auto-completado con `Ctrl+Space` y ves:

    * `main`: el archivo `main.py` (el "módulo" de Python).
    * `app`: el objeto creado dentro de `main.py` con la línea `app = FastAPI()`.
    * `--reload`: hace que el servidor se reinicie cada vez que cambia el código. Úsalo únicamente para desarrollo.

En el output, hay una línea que dice más o menos:

```hl_lines="4"
INFO:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```
