## Anwendungsfälle { #use-cases }

Sie könnten dies verwenden, um Daten von einem **AI LLM**-Service, aus **Logs** oder **Telemetrie**, oder aus anderen Typen von Daten zu streamen, die sich in **JSON**-Items strukturieren lassen.

     * Automatically accept changes that are valid property upgrades of a getter or setter.
     *
     * Here we automatically accept the following cases:
     * - A setter `setX` of an upgraded property is removed
     * - A boolean `isX` of an upgraded property is removed
     * - A new getter `getX` is added, where the old getter is a boolean getter `isX` of an upgraded property

Wenn Sie jedoch **reine Binärdaten** oder Strings streamen möchten, so können Sie es machen.

Sadece `str` yerine `str | None` kullanmak, aslında değer `None` olabilecekken her zaman `str` olduğunu varsaydığınız hataları editörün yakalamanıza yardımcı olur.

### Tip olarak sınıflar { #classes-as-types }

Bir sınıfı da bir değişkenin tipi olarak bildirebilirsiniz.

Örneğin, adı olan bir `Person` sınıfınız olsun:

{* ../../docs_src/python_types/tutorial010_py310.py hl[1:3] *}

////

Використання `str | None` замість просто `str` дозволить редактору допомогти вам виявити помилки, коли ви могли б вважати, що значенням завжди є `str`, хоча насправді воно також може бути `None`.

### Класи як типи { #classes-as-types }

Ви також можете оголосити клас як тип змінної.

Скажімо, у вас є клас `Person` з імʼям:

{* ../../docs_src/python_types/tutorial010_py310.py hl[1:3] *}
