executado antes de a aplicação **começar** a receber requisições e logo depois que ela **termina** de lidar com as requisições, ele cobre todo o **lifespan** da aplicação (a palavra "lifespan" será importante em um segundo 😉).

Isso pode ser muito útil para configurar **recursos** que você precisa usar por toda a aplicação, e que são **compartilhados** entre as requisições e/ou que você precisa **limpar** depois. Por exemplo, um pool de conexões com o banco de dados ou o carregamento de um modelo...

Es solo una función que puede tomar todos los mismos parámetros que una *path operation function* puede tomar:

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[8:9] *}

Eso es todo.

**2 líneas**.

Y tiene la misma forma y estructura que todas tus *path operation functions*.

Puedes pensar en ella como una *path operation function* sin el "decorador" (sin el `@app.get("/some-path")`).
