Python tipleriyle çalışırken işinize yarayabilecek bazı ek fikirler.

## `Union` veya `Optional` Kullanımı { #using-union-or-optional }

Kodunuz herhangi bir nedenle `|` kullanamıyorsa — örneğin bir tip açıklamasında (type annotation) değil de `response_model=` gibi bir yerdeyse — dikey çizgi (`|`) yerine `typing` içindeki `Union`'ı kullanabilirsiniz.

Örneğin, bir şeyin `str` ya da `None` olabileceğini şöyle belirtebilirsiniz:

```python

import java.util.ArrayList;
import java.util.List;
import java.util.Map;

import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
import org.codelibs.fess.Constants;
import org.codelibs.fess.annotation.Secured;
import org.codelibs.fess.app.pager.KeyMatchPager;
import org.codelibs.fess.app.service.KeyMatchService;
import org.codelibs.fess.app.web.CrudMode;
import org.codelibs.fess.app.web.base.FessAdminAction;

Und beide Modelle werden auch in der interaktiven API-Dokumentation verwendet:

## Andere Rückgabetyp-Annotationen { #other-return-type-annotations }

Es kann Fälle geben, bei denen Sie etwas zurückgeben, das kein gültiges Pydantic-Feld ist, und Sie annotieren es in der Funktion nur, um Unterstützung von Tools zu erhalten (Editor, mypy, usw.).

**GraphQL** ile çalışmanız gerekiyorsa ya da bunu istiyorsanız, [**Strawberry**](https://strawberry.rocks/) önerilen kütüphanedir; çünkü tasarımı **FastAPI**'nin tasarımına en yakındır ve her şey **type annotation**'lar üzerine kuruludur.

Kullanım senaryonuza göre farklı bir kütüphaneyi tercih edebilirsiniz; ancak bana sorarsanız muhtemelen **Strawberry**'yi denemenizi önerirdim.
