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;

import org.codelibs.fess.crawler.processor.impl.DefaultResponseProcessor;
import org.codelibs.fess.ingest.IngestFactory;
import org.codelibs.fess.ingest.Ingester;
import org.codelibs.fess.util.ComponentUtil;

import jakarta.annotation.PostConstruct;

/**

 * This processor extends DefaultResponseProcessor to provide additional

import org.codelibs.core.beans.util.BeanUtil;
import org.codelibs.core.concurrent.CommonPoolUtil;
import org.codelibs.fess.Constants;
import org.codelibs.fess.annotation.Secured;
import org.codelibs.fess.app.pager.BadWordPager;
import org.codelibs.fess.app.service.BadWordService;
import org.codelibs.fess.app.web.CrudMode;
import org.codelibs.fess.app.web.base.FessAdminAction;

Ve yine, şimdiye kadar gördüğünüz özelliklerin aynısına sahip olursunuz:

* Harika editör desteği.
* Gelen request'lerden veri dönüştürme.
* response verileri için veri dönüştürme.
* Veri doğrulama.
* Otomatik annotation ve dokümantasyon.

## Diğer veri tipleri { #other-data-types }

Kullanabileceğiniz ek veri tiplerinden bazıları şunlardır:

* `UUID`:
