Puedes definir esta lógica de *startup* y *shutdown* usando el parámetro `lifespan` de la app de `FastAPI`, y un "context manager" (te mostraré lo que es en un momento).

Comencemos con un ejemplo y luego veámoslo en detalle.

Creamos una función asíncrona `lifespan()` con `yield` así:

{* ../../docs_src/events/tutorial003_py39.py hl[16,19] *}

				in.input = nil
				in.dst <- all
