then the internal variable `__name__` in your file, created automatically by Python, will have as value the string `"__main__"`.

So, the section:

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

will run.

This won't happen if you import that module (file).

So, if you have another file `importer.py` with:

```Python
from myapp import app

	res.Hosts = hosts
	ready := make(chan struct{})
	ctx, cancel := context.WithCancel(context.Background())
	res.cancel = cancel
	for i, host := range hosts {
		manager, err := NewManager(ctx, ManagerOptions{
			Dialer: ConnectWS(dialer.DialContext,
				dummyNewToken,
				nil),
			Local:        host,
			Hosts:        hosts,
			AuthFn:       dummyNewToken,
			AuthToken:    dummyTokenValidate,
			BlockConnect: ready,

        }

        return new SpnegoContext(tc.getConfig(), setupTargetName(tc, host, new NtlmContext(tc, this, doSigning)));
    }

    private static SSPContext setupTargetName(CIFSContext tc, String host, NtlmContext ntlmContext) {
        if (host != null && tc.getConfig().isSendNTLMTargetName()) {
            ntlmContext.setTargetName(String.format("cifs/%s", host));
        }
        return ntlmContext;
    }
