At the same point, you try to trigger the autocomplete with `Ctrl+Space` and you see:

<img src="/img/python-types/image02.png">

With that, you can scroll, seeing the options, until you find the one that "rings a bell":

<img src="/img/python-types/image03.png">

## More motivation

Check this function, it already has type hints:

{* ../../docs_src/python_types/tutorial003.py hl[1] *}

		return nil
	})
	if !errors.Is(err, context.Canceled) {
		t.Error("expected context.Canceled, got", err)
	}
}

// testServerStreamNoPing will test if server and client handle no pings.
func testServerStreamNoPing(t *testing.T, local, remote *Manager, inCap int) {
	defer testlogger.T.SetErrorTB(t)()
	errFatal := func(err error) {
		t.Helper()
		if err != nil {
			t.Fatal(err)
		}
