Ve yine, editör bunun bir `str` ​​olduğunu biliyor ve bunun için destek sağlıyor.

#### `Tuple` ve `Set`

`Tuple` ve `set`lerin tiplerini bildirmek için de aynısını yapıyoruz:

{* ../../docs_src/python_types/tutorial007.py hl[1,4] *}


Bu şu anlama geliyor:

* `items_t` değişkeni sırasıyla `int`, `int`, ve `str` tiplerinden oluşan bir `tuple` türündedir .
* `items_s` ise her öğesi `bytes` türünde olan bir `set` örneğidir.

    /**
     * Creates a thumbnail generation task.
     * @param path The path to the source document.
     * @param docMap The document map containing metadata.
     * @return A tuple containing task information.
     */
    Tuple3<String, String, String> createTask(String path, Map<String, Object> docMap);

        return defaultSettings;
    }

    private List<Tuple<String, Object>> defaultArraySettings() {
        final List<Tuple<String, Object>> tuples = new ArrayList<>();
        tuples.add(new Tuple<>(DefaultKeys.SUPPORTED_FIELDS, "content"));
        return tuples;
    }

    /**
     * Loads the index settings from a resource file.

        final Tuple3<String, String, String> task = new Tuple3<>(getName(), thumbnailId, path);
        if (logger.isDebugEnabled()) {
            logger.debug("Create thumbnail task: {}", task);
        }
        return task;
    }

    /**
     * Generates a thumbnail image and saves it to the specified output file.
     *

#### Tupel und Menge { #tuple-and-set }

Das Gleiche gilt für die Deklaration eines Tupels – `tuple` – und einer Menge – `set`:

{* ../../docs_src/python_types/tutorial007_py39.py hl[1] *}

Das bedeutet:

* Die Variable `items_t` ist ein `tuple` mit 3 Elementen, einem `int`, einem weiteren `int` und einem `str`.
