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

      socketHost = address.url.host
      socketPort = address.url.port
    } else {
      val proxyAddress = proxy.address()
      require(proxyAddress is InetSocketAddress) {
        "Proxy.address() is not an InetSocketAddress: ${proxyAddress.javaClass}"
      }
      socketHost = proxyAddress.socketHost
      socketPort = proxyAddress.port
    }

    if (socketPort !in 1..65535) {

    /**

Fangen wir mit einem einfachen Beispiel an:

Dieses Programm gibt aus:
