Y como la operación de escritura no usa `async` y `await`, definimos la función con un `def` normal:

{* ../../docs_src/background_tasks/tutorial001_py39.py hl[6:9] *}

## Agregar la tarea en segundo plano { #add-the-background-task }

Dentro de tu *path operation function*, pasa tu función de tarea al objeto de *background tasks* con el método `.add_task()`:
