### Otras formas de código asíncrono { #other-forms-of-asynchronous-code }

Este estilo de usar `async` y `await` es relativamente nuevo en el lenguaje.

Pero hace que trabajar con código asíncrono sea mucho más fácil.

# Declarar Ejemplos de Request { #declare-request-example-data }

Puedes declarar ejemplos de los datos que tu aplicación puede recibir.

Aquí tienes varias formas de hacerlo.

## Datos extra de JSON Schema en modelos de Pydantic { #extra-json-schema-data-in-pydantic-models }

Puedes declarar `examples` para un modelo de Pydantic que se añadirá al JSON Schema generado.
