ng pull requests</a> for your language. You can filter the pull requests by the ones with the label for your language. For example, for Spanish, the label is <a href="https://github.com/tiangolo/fastapi/pulls?q=is%3Aopen+sort%3Aupdated-desc+label%3Alang-es+label%3Aawaiting-review" class="external-link" target="_blank">`lang-es`</a>.

* Review those pull requests, requesting changes or approving them. For the languages I don't speak, I'll wait for several others to review the translation...

from fastapi import FastAPI, Response

app = FastAPI()


@app.get("/headers-and-object/")
def get_headers(response: Response):
    response.headers["X-Cat-Dog"] = "alone in the world"

By default it will listen on the IP address `127.0.0.1`, which is the IP for your machine to communicate with itself alone (`localhost`).

## `fastapi run`

When you run `fastapi run`, it will run on production mode by default.

It will have **auto-reload disabled** by default.

target="_blank">aktuellen Pull Requests</a> für Ihre Sprache. Sie können die Pull Requests nach dem Label für Ihre Sprache filtern. Für Spanisch lautet das Label beispielsweise <a href="https://github.com/tiangolo/fastapi/pulls?q=is%3Aopen+sort%3Aupdated-desc+label%3Alang-es+label%3Aawaiting-review" class="external-link" target="_blank">`lang-es`</a>.

* Sehen Sie diese Pull Requests durch (Review), schlagen Sie Änderungen vor, oder segnen Sie sie ab (Approval). Bei den Sprachen, die ich nicht spreche, warte...

Buna ek olarak Python'un **Veri Bilimi**, Makine Öğrenimi ve özellikle Derin Öğrenme için ana dil olduğu gerçeği, FastAPI'yi Veri Bilimi / Makine Öğrenimi web API'leri ve uygulamaları için çok iyi bir seçenek haline getirir.

Production'da nasıl oldugunu görmek için şu bölüme bakın [Deployment](deployment/index.md){.internal-link target=_blank}.

## `async` ve `await`

    ```

!!! note
    Keep in mind that in this case, FastAPI won't check the contents of the list.

    For example, `List[int]` would check (and document) that the contents of the list are integers. But `list` alone wouldn't.

## Declare more metadata

You can add more information about the parameter.

That information will be included in the generated OpenAPI and used by the documentation user interfaces and external tools.

## Ön Tanımlı Değerler

Eğer *yol parametresi* alan bir *yol operasyonunuz* varsa ve alabileceği *yol parametresi* değerlerinin ön tanımlı olmasını istiyorsanız, standart Python <abbr title="Enumeration">`Enum`</abbr> tipini kullanabilirsiniz.

### Bir `Enum` Sınıfı Oluşturalım

`Enum` sınıfını projemize dahil edip `str` ile `Enum` sınıflarını miras alan bir alt sınıf yaratalım.

### Zrozum pytanie

* Upewnij się, czy rozumiesz **cel** i przypadek użycia osoby pytającej.

* Następnie sprawdź, czy pytanie (większość to pytania) jest **jasne**.

* W wielu przypadkach zadane pytanie dotyczy rozwiązania wymyślonego przez użytkownika, ale może istnieć **lepsze** rozwiązanie. Jeśli dokładnie zrozumiesz problem i przypadek użycia, być może będziesz mógł zaproponować lepsze **alternatywne rozwiązanie**.

    * 也可以在现有 PR 中通过你使用的语言标签来筛选对应的 PR，举个例子，对于西班牙语，标签是 <a href="https://github.com/tiangolo/fastapi/pulls?q=is%3Apr+is%3Aopen+sort%3Aupdated-desc+label%3Alang-es+label%3A%22awaiting+review%22" class="external-link" target="_blank">`lang-es`</a>。

* 请使用相同的 Python 示例，且只需翻译文档中的文本，不用修改其它东西。

* 请使用相同的图片、文件名以及链接地址，不用修改其它东西。
