então a variável interna `__name__` no seu arquivo, criada automaticamente pelo Python, terá como valor a string `"__main__"`.

Então, a seção:

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

vai executar.

Isso não acontecerá se você importar esse módulo (arquivo).

Então, se você tiver outro arquivo `importer.py` com:

```Python
from myapp import app

### There are no limits on how many server pools can be combined

```
minio server http://host{1...32}/export{1...32} http://host{1...12}/export{1...12}
```

In above example there are two server pools

- 32 * 32 = 1024 drives pool1
- 12 * 12 = 144 drives pool2

</div>

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
