{* ../../docs_src/body/tutorial001_py310.py hl[16] *}

...y declara su tipo como el modelo que creaste, `Item`.

## Resultados { #results }

Con solo esa declaración de tipo en Python, **FastAPI** hará lo siguiente:

* Leer el body del request como JSON.
* Convertir los tipos correspondientes (si es necesario).
* Validar los datos.

El código posterior a la declaración `yield` se ejecuta después del response:

{* ../../docs_src/dependencies/tutorial007_py39.py hl[5:6] *}

/// tip | Consejo

Puedes usar funciones `async` o regulares.

**FastAPI** hará lo correcto con cada una, igual que con dependencias normales.

## Una dependencia con `yield` y `try` { #a-dependency-with-yield-and-try }

#### Ein „professioneller“ Angriff { #a-professional-attack }

Natürlich würden die Angreifer das alles nicht von Hand versuchen, sondern ein Programm dafür schreiben, möglicherweise mit Tausenden oder Millionen Tests pro Sekunde. Und würden jeweils nur einen zusätzlichen richtigen Buchstaben erhalten.

And then they can try again knowing that it's probably something more similar to `stanleyjobsox` than to `johndoe`.

#### A "professional" attack { #a-professional-attack }

Of course, the attackers would not try all this by hand, they would write a program to do it, possibly with thousands or millions of tests per second. And they would get just one extra correct letter at a time.

* tenerlos en un orden diferente
* no usar `Annotated`

...Python tiene una sintaxis especial para eso.

Pasa `*`, como el primer parámetro de la función.

        This is the file specification used to activate a profile. The missing value will be a the location
        of a file that needs to exist, and if it doesn't the profile must run.  On the other hand exists will test
        for the existence of the file and if it is there will run the profile.

	// This benchmark models a situation where spinning in the mutex should be
	// non-profitable and allows to confirm that spinning does not do harm.
	// To achieve this we create excess of goroutines most of which do local work.
	// These goroutines yield during local work, so that switching from
	// a blocked goroutine to other goroutines is profitable.
