entonces la variable interna `__name__` en tu archivo, creada automáticamente por Python, tendrá como valor el string `"__main__"`.

Así que, la sección:

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

se ejecutará.

---

Esto no ocurrirá si importas ese módulo (archivo).

Entonces, si tienes otro archivo `importer.py` con:

```Python
from myapp import app

```

</div>

то встроенная переменная `__name__`, автоматически создаваемая Python в вашем файле, будет иметь значение строкового типа `"__main__"`.

Тогда эта часть кода:

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

будет запущена.

---

Но этого не произойдет, если вы импортируете этот модуль (файл).

Таким образом, если у вас есть файл `importer.py` с таким импортом:

```Python

        client_max_body_size 0;
        # To disable buffering
        proxy_buffering off;
        proxy_request_buffering off;

        location / {
            proxy_set_header Host $http_host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Forwarded-Proto $scheme;

            return false;
        }
    }

    private static boolean isLocal(String host) {
        return "localhost".equals(host) || "127.0.0.1".equals(host);
