dann hat in Ihrer Datei die interne Variable `__name__`, die von Python automatisch erstellt wird, als Wert den String `"__main__"`.

Daher wird der Abschnitt:

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

ausgeführt.

Dies wird nicht passieren, wenn Sie das Modul (die Datei) importieren.

Wenn Sie also eine weitere Datei `importer.py` mit folgendem Inhalt haben:

```Python

			Timeout:   30 * time.Second,
			KeepAlive: 30 * time.Second,
		}).DialContext
	}

	return func(ctx context.Context, network, addr string) (conn net.Conn, err error) {
		host, port, err := net.SplitHostPort(addr)
		if err != nil {
			return nil, err
		}

		if net.ParseIP(host) != nil {
			// For IP only setups there is no need for DNS lookups.
			return baseDialCtx(ctx, "tcp", addr)
		}
