Wir importieren das Submodul `items` direkt, anstatt nur seine Variable `router` zu importieren.

Das liegt daran, dass wir im Submodul `users` auch eine weitere Variable namens `router` haben.

Wenn wir eine nach der anderen importiert hätten, etwa:

```Python
from .routers.items import router
from .routers.users import router
```

Вместо того чтобы импортировать только переменную `router`, мы импортируем непосредственно суб-модуль `items`.

Мы делаем это потому, что у нас есть ещё одна переменная `router` в суб-модуле `users`.

Если бы мы импортировали их одну за другой, как показано в примере:

```Python
from .routers.items import router
from .routers.users import router
```

    AtomicDoubleArray aa = new AtomicDoubleArray(SIZE);
    for (int i = 0; i < SIZE; i++) {
      aa.set(i, (double) COUNTDOWN);
    }
    Counter c1 = new Counter(aa);
    Counter c2 = new Counter(aa);
    Thread t1 = newStartedThread(c1);
    Thread t2 = newStartedThread(c2);
    awaitTermination(t1);
    awaitTermination(t2);
    assertEquals(SIZE * COUNTDOWN, c1.counts + c2.counts);

  }

  public void testOnlyOneOpen() throws Exception {
    ByteSource source = newByteSource(0, 50);
    int[] counter = new int[1];
    ByteSource checker =
        new ByteSource() {
          @Override
          public InputStream openStream() throws IOException {
            if (counter[0]++ != 0) {
              throw new IllegalStateException("More than one source open");
            }

Estamos importando o submódulo `items` diretamente, em vez de importar apenas sua variável `router`.

Isso ocorre porque também temos outra variável chamada `router` no submódulo `users`.

Se tivéssemos importado um após o outro, como:

```Python
from .routers.items import router
from .routers.users import router
```

o `router` de `users` sobrescreveria o de `items` e não poderíamos usá-los ao mesmo tempo.

	"testing"

	"github.com/minio/mux"
)

// Test cross domain xml handler.
func TestCrossXMLHandler(t *testing.T) {
	// Server initialization.
	router := mux.NewRouter().SkipClean(true).UseEncodedPath()
	handler := setCrossDomainPolicyMiddleware(router)
	srv := httptest.NewServer(handler)

	resp, err := http.Get(srv.URL + crossDomainXMLEntity)
	if err != nil {
		t.Fatal(err)
	}

We are importing the submodule `items` directly, instead of importing just its variable `router`.

This is because we also have another variable named `router` in the submodule `users`.

If we had imported one after the other, like:

```Python
from .routers.items import router
from .routers.users import router
```
