```Python
with open("file.txt") as file:
    file.read()
```

У новіших версіях Python також є асинхронний менеджер контексту. Його використовують з `async with`:

```Python
async with lifespan(app):
    await do_stuff()
```

Коли ви створюєте менеджер контексту або асинхронний менеджер контексту, як вище, перед входом у блок `with` буде виконано код перед `yield`, а після виходу з блоку `with` буде виконано код після `yield`.
