## Set-Typen { #set-types }

Aber dann denken wir darüber nach und stellen fest, dass sich die Tags nicht wiederholen sollen, es sollen eindeutige Strings sein.

Python hat einen Datentyp speziell für Mengen eindeutiger Dinge: das <abbr title="Menge">`set`</abbr>.

Deklarieren wir also `tags` als Set von Strings.

                    req.setFileInformation(new FileBasicInfo(ctime, atime, mtime, 0L, attrs));
                    dh.send(req);
                } else if (dh.hasCapability(SmbConstants.CAP_NT_SMBS)) {
                    // use the open file descriptor
                    dh.send(new Trans2SetFileInformation(dh.getConfig(), dfd.getFid(), attrs, ctime, mtime, atime),

Alerting with prometheus is two step process. First we setup alerts in Prometheus server and then we need to send alerts to the AlertManager.

        }
    }

    @Override
    public void send(ByteBuffer data, RdmaMemoryRegion region) throws IOException {
        if (state != RdmaConnectionState.ESTABLISHED && state != RdmaConnectionState.CONNECTED) {
            throw new IOException("Connection not established");
        }

        try {
            // In real implementation, this would send using DiSNI:

You can use Pydantic's model configuration to `forbid` any `extra` fields:

{* ../../docs_src/request_form_models/tutorial002_an_py39.py hl[12] *}

If a client tries to send some extra data, they will receive an **error** response.

For example, if the client tries to send the form fields:

* `username`: `Rick`
* `password`: `Portal Gun`
* `extra`: `Mr. Poopybutthole`

```console
$ pip install python-multipart
```

This is because uploaded files are sent as "form data".

///

## Import `File` { #import-file }

Import `File` and `UploadFile` from `fastapi`:

{* ../../docs_src/request_files/tutorial001_an_py39.py hl[3] *}

Das bedeutet, dass Clients, die Ihre API verwenden, nicht prüfen müssen, ob der Wert vorhanden ist oder nicht. Sie können davon ausgehen, dass das Feld immer vorhanden ist. In einigen Fällen hat es jedoch nur den Defaultwert `None`.

Um dies in OpenAPI zu kennzeichnen, markieren Sie dieses Feld als **erforderlich**, da es immer vorhanden sein wird.
