Yukarıdaki içeriği bir `main.py` dosyasına kopyalayalım.

Uygulamayı çalıştıralım:

<div class="termy">

```console
$ uvicorn main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
<span style="color: green;">INFO</span>:     Started reloader process [28720]

          @Override
          public Object load(Object key) {
            loadCount.incrementAndGet();
            return new Object();
          }

          @Override
          public ListenableFuture<Object> reload(Object key, Object oldValue) {
            reloadCount.incrementAndGet();
            return immediateFuture(new Object());
          }

          @Override
          public Map<Object, Object> loadAll(Iterable<?> keys) {

  }

  @GwtIncompatible // Executor + Futures

          @Override
          public Object load(Object key) {
            loadCount.incrementAndGet();
            return new Object();
          }

          @Override

          }

          @Override
          public Map<Object, Object> loadAll(Iterable<?> keys) {

	if objAPI == nil {
		return np, grid.NewRemoteErr(errServerNotInitialized)
	}

	go func() {
		err := globalTierConfigMgr.Reload(context.Background(), newObjectLayerFn())

	return np, nerr
}

// ConsoleLogHandler sends console logs of this node back to peer rest client

```console
$ uvicorn main:app --reload

</div>

아래처럼 앱을 만든다면:

{* ../../docs_src/first_steps/tutorial002.py hl[3] *}

이를 `main.py` 파일에 넣고, `uvicorn`을 아래처럼 호출해야 합니다:

<div class="termy">

```console
$ uvicorn main:my_awesome_api --reload

    @Override
    public Integer load(Integer key) {
      countLoad.incrementAndGet();
      return key;
    }

    @GwtIncompatible // reload
    @Override
    public ListenableFuture<Integer> reload(Integer key, Integer oldValue) {
      countReload.incrementAndGet();
      return immediateFuture(oldValue + 1);
    }

    public int getLoadCount() {

     * @throws IOException if any
     * @throws XmlPullParserException if any
     */
    Settings buildSettings() throws IOException, XmlPullParserException;

    /**
     * @param useCachedSettings if true, doesn't reload the user settings
     * @return a <code>Settings</code> object from the user settings file.
     * @throws IOException if any
     * @throws XmlPullParserException if any
     */

        new CacheLoader<Object, Object>() {
          @Override
          public Object load(Object key) {
            return one;
          }

          @Override
          public ListenableFuture<Object> reload(Object key, Object oldValue) {
            return immediateFuture(two);
          }
        };

    LoadingCache<Object, Object> cache = CacheBuilder.newBuilder().recordStats().build(loader);

```console
$ hypercorn main:app --bind 0.0.0.0:80

Running on 0.0.0.0:8080 over http (CTRL + C to quit)
```

</div>

/// warning

N'oubliez pas de supprimer l'option `--reload` si vous l'utilisiez.

 L'option `--reload` consomme beaucoup plus de ressources, est plus instable, etc.

 Cela aide beaucoup pendant le **développement**, mais vous **ne devriez pas** l'utiliser en **production**.
