Si vous l'exécutez avec :

<div class="termy">

```console
$ python myapp.py
```

</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.

## Rode o código

Todos os blocos de código podem ser copiados e utilizados diretamente (eles são, na verdade, arquivos Python testados).
