alors la variable interne `__name__` de votre fichier, créée automatiquement par Python, aura pour valeur la chaîne de caractères `"__main__"`.

Ainsi, la section :

```Python
    uvicorn.run(app, host="0.0.0.0", port=8000)
```

va s'exécuter.

Cela ne se produira pas si vous importez ce module (fichier).

Par exemple, si vous avez un autre fichier `importer.py` qui contient :

```Python

    assertTrue("Heap is not intact initially", mmHeap.isIntact());
    Iterator<Integer> it = mmHeap.iterator();
    assertEquals((Integer) 1, it.next());
    assertEquals((Integer) 20, it.next());
    assertEquals((Integer) 1000, it.next());
    assertEquals((Integer) 2, it.next());
    it.remove();
    // After this remove, 400 has moved up and 20 down past cursor
    assertTrue("Heap is not intact after remove", mmHeap.isIntact());

    assertTrue("Heap is not intact initially", mmHeap.isIntact());
    Iterator<Integer> it = mmHeap.iterator();
    assertEquals((Integer) 1, it.next());
    assertEquals((Integer) 20, it.next());
    assertEquals((Integer) 1000, it.next());
    assertEquals((Integer) 2, it.next());
    it.remove();
    // After this remove, 400 has moved up and 20 down past cursor
    assertTrue("Heap is not intact after remove", mmHeap.isIntact());

그리고 나머지는 **FastAPI**에 의해 처리됩니다.

실행하면 <a href="http://localhost:8000/v1/" class="external-link" target="_blank">http://localhost:8000/v1/</a>으로 이동해서 Flask의 응답을 볼 수 있습니다:

```txt
Hello, World from Flask!
```

그리고 다음으로 이동하면 <a href="http://localhost:8000/v2" class="external-link" target="_blank">http://localhost:8000/v2</a> Flask의 응답을 볼 수 있습니다:

      entries[i] = ImmutableMap.entryOf(i, i);
    }

    ImmutableMap<Integer, Integer> map = RegularImmutableMap.fromEntries(entries);
    Set<Integer> keySet = map.keySet();

/// tip | "Dica"

O IP `0.0.0.0` é comumente usado para significar que o programa escuta em todos os IPs disponíveis naquela máquina/servidor.

Ce qui fait qu'avec une URL comme :

```
http://localhost:8000/items/?q=foo&q=bar
```

vous recevriez les valeurs des multiples paramètres de requête `q` (`foo` et `bar`) dans une `list` Python au sein de votre fonction de **path operation**, dans le paramètre de fonction `q`.

/// tip

The IP `0.0.0.0` is commonly used to mean that the program listens on all the IPs available in that machine/server.
