Ми імпортуємо підмодуль `items` напряму, замість імпорту лише його змінної `router`.

Це тому, що в підмодулі `users` також є змінна з назвою `router`.

Якби ми імпортували один за одним, як:

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

`router` з `users` перезаписав би той, що з `items`, і ми не змогли б використовувати їх одночасно.

Nous importons le sous-module `items` directement, au lieu d'importer uniquement sa variable `router`.

C'est parce que nous avons également une autre variable nommée `router` dans le sous-module `users`.

Si nous les avions importées l'une après l'autre, comme :

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

@router_b.get("/")
def get_b():
    return {"msg": "B"}


@router_c.get("/")
def get_c():
    return {"msg": "C"}


router_b.include_router(router=router_c, prefix="/c")
router_a.include_router(router=router_b, prefix="/b")
app.include_router(router=router_a, prefix="/a")


client = TestClient(app)


@pytest.mark.parametrize(
    "path,expected_status,expected_response",
    [

    int numThreads = 10;
    ExecutorService executor = newFixedThreadPool(numThreads);
    for (int i = 0; i < 1000; i++) {
      AtomicInteger counter = new AtomicInteger();
      TrustedListenableFutureTask<Integer> task =
          TrustedListenableFutureTask.create(counter::incrementAndGet);
      CyclicBarrier barrier = new CyclicBarrier(numThreads + 1);
      Runnable wrapper =
          () -> {

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
```
