# Tarefas em segundo plano { #background-tasks }

Você pode definir tarefas em segundo plano para serem executadas *após* retornar uma resposta.

Isso é útil para operações que precisam acontecer após uma request, mas que o cliente não precisa realmente esperar a operação terminar antes de receber a resposta.

Isso inclui, por exemplo:

* Notificações por e-mail enviadas após realizar uma ação:

@pytest.fixture(
    name="client",
    params=[
        pytest.param("tutorial004_py310", marks=needs_py310),
    ],
)
def get_client(request: pytest.FixtureRequest):
    mod = importlib.import_module(f"docs_src.body_nested_models.{request.param}")

    client = TestClient(mod.app)
    return client


def test_put_all(client: TestClient):
    response = client.put(
        "/items/123",

flagged as a TODO by the automated tooling. That is true even for proposals that add API.

Use the following forms in your markdown:

	[http.Request]                     # symbol documentation; auto-linked as in Go doc strings
	[Request]                          # short form, for symbols in the package being documented
	[net/http]                         # package link
	[#12345](/issue/12345)             # GitHub issues

			lc.Rules[i].ID = uuid.New().String()
		}
	}
	return &lc, nil
}

// ParseLifecycleConfig - parses data in given reader to Lifecycle.
func ParseLifecycleConfig(reader io.Reader) (*Lifecycle, error) {
	var lc Lifecycle
	if err := xml.NewDecoder(reader).Decode(&lc); err != nil {
		return nil, err
	}
	return &lc, nil
}

// Validate - validates the lifecycle configuration
