In beiden Fällen bedeutet das, dass `item` ein `int` oder ein `str` sein kann.

#### Vielleicht `None`

Sie können deklarieren, dass ein Wert ein `str`, aber vielleicht auch `None` sein kann.

In Python 3.6 und darüber (inklusive Python 3.10) können Sie das deklarieren, indem Sie `Optional` vom `typing` Modul importieren und verwenden.

						return
					}
					// Use NOOP filter because the download failed.
					newExtensionConfig, err = createHTTPAllowAllFilter(extConfig.GetName())
					if err != nil {
						// If the fallback is failing, send the Nack regardless of fail_open.
						err = fmt.Errorf("failed to create allow-all filter as a fallback of %s Wasm Module: %w", extConfig.GetName(), err)
						convertErrs[i] = err
						return
					}
				}

Indem Sie von `str` erben, weiß die API Dokumentation, dass die Werte des Enums vom Typ `str` sein müssen, und wird in der Lage sein, korrekt zu rendern.

Erstellen Sie dann Klassen-Attribute mit festgelegten Werten, welches die erlaubten Werte sein werden:

```Python hl_lines="1  6-9"

```
