**FastAPI** no existiría si no fuera por el trabajo previo de otros.

Ha habido muchas herramientas creadas antes que han ayudado a inspirar su creación.

#### `.dict()` de Pydantic { #pydantics-dict }

`user_in` es un modelo Pydantic de la clase `UserIn`.

Los modelos Pydantic tienen un método `.dict()` que devuelve un `dict` con los datos del modelo.

Así que, si creamos un objeto Pydantic `user_in` como:

```Python
user_in = UserIn(username="john", password="secret", email="******@****.***")
```

y luego llamamos a:

```Python
user_dict = user_in.dict()
```
