</div>

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

Тогда выполнится условие и 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

	if err != nil {
		t.Fatal(err)
	}
	req.RequestURI = "/?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=USWUXHGYZQYFYFFIT3RE%2F20170529%2Fus-east-1%2Fs3%2Faws4_request&X-Amz-Date=20170529T190139Z&X-Amz-Expires=600&X-Amz-Signature=19b58080999df54b446fc97304eb8dda60d3df1812ae97f3e8783351bfd9781d&X-Amz-SignedHeaders=host&prefix=Hello%2AWorld%2A"

  }

  @Test fun testHostname() {
    val headers = headersOf("Host", "host-from-header.com")
    val socket =
      MockWebServerSocket(
        FakeSocket(
          localAddress =
            InetAddress.getByAddress(
              "host-from-address.com",
              byteArrayOf(0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1),
            ),

            return false;
        }
    }

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

    /**
     * Checks the URL to see if this repository refers to a non-localhost repository using HTTP.
     *
     * @param originalRepository

  /**
   * A map of contents pre-created before experiment starts to only measure map creation cost. The
   * implementation for the creation of contents is independent and could be different from that of
   * the map under test.
   */
  Map<Element, Element> contents;

  /** Map pre-created before experiment starts to only measure iteration cost during experiment. */
  Map<Element, Element> map;

  CollectionBenchmarkSampleData elems;

```

</div>

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

		case "ID":
			err = dc.ReadExactBytes((z.ID)[:])
			if err != nil {
				err = msgp.WrapError(err, "ID")
				return
			}
		case "Host":
			z.Host, err = dc.ReadString()
			if err != nil {
				err = msgp.WrapError(err, "Host")
				return
			}
		case "Time":
			z.Time, err = dc.ReadTime()
			if err != nil {
				err = msgp.WrapError(err, "Time")
				return
			}
