That converts the function into something called an "**async context manager**".

{* ../../docs_src/events/tutorial003_py39.py hl[1,13] *}

A **context manager** in Python is something that you can use in a `with` statement, for example, `open()` can be used as a context manager:

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

		t.Fatalf("unexpected error: %v", err)
	}
	if err := ps.Subscribe(MaskAll, ch2, doneCh2, nil); err != nil {
		t.Fatalf("unexpected error: %v", err)
	}

	close(doneCh1)
	// Allow for the above statement to take effect.
	time.Sleep(100 * time.Millisecond)
	ps.Lock()
	if len(ps.subs) != 1 {
		t.Fatal("expected 1 subscriber")
	}
	ps.Unlock()
	close(doneCh2)
}

Un **context manager** en Python es algo que puedes usar en un statement `with`, por ejemplo, `open()` puede ser usado como un context manager:
