### Функція тривалості життя { #lifespan-function }

Перше, на що слід звернути увагу: ми визначаємо асинхронну функцію з `yield`. Це дуже схоже на залежності з `yield`.

{* ../../docs_src/events/tutorial003_py310.py hl[14:19] *}

Перша частина функції до `yield` буде виконана перед запуском застосунку.

А частина після `yield` буде виконана після завершення роботи застосунку.

        // NameOffset field (2 bytes) - should be 16 (after header)
        assertEquals(16, SMBUtil.readInt2(buffer, 4));

        // NameLength field (2 bytes) - should be 4 for "RqLs"
        assertEquals(4, SMBUtil.readInt2(buffer, 6));

		t.Errorf("Name fields shouldn't be changed if untouched, but got %v", animal.Name)

The first thing to notice, is that we are defining an async function with `yield`. This is very similar to Dependencies with `yield`.

{* ../../docs_src/events/tutorial003_py310.py hl[14:19] *}

The first part of the function, before the `yield`, will be executed **before** the application starts.

And the part after the `yield` will be executed **after** the application has finished.
