### Nur modernes Python

Alles basiert auf **Python 3.8 Typ**-Deklarationen (dank Pydantic). Es muss keine neue Syntax gelernt werden, nur standardisiertes modernes Python.

Wenn Sie eine zweiminütige Auffrischung benötigen, wie man Python-Typen verwendet (auch wenn Sie FastAPI nicht benutzen), schauen Sie sich das kurze Tutorial an: [Einführung in Python-Typen](python-types.md){.internal-link target=_blank}.

/// warning | "Achtung"

`ujson` ist bei der Behandlung einiger Sonderfälle weniger sorgfältig als Pythons eingebaute Implementierung.

/// tip | "Tipp"

Möglicherweise ist `ORJSONResponse` eine schnellere Alternative.

clang-format <my_cc_file> --style=google > /tmp/my_cc_file.cc

```

#### Python coding style

Changes to TensorFlow Python code should conform to
[Google Python Style Guide](https://github.com/google/styleguide/blob/gh-pages/pyguide.md)

Use `pylint` to check your Python changes. To install `pylint` and check a file
with `pylint` against TensorFlow's custom style definition:

```bash

# for choosing the final directory name. This adds "-devYYYYMMDD" to the end of
# the version string (.devYYYYMMDD for Python; see pypi.org/project/tf-nightly)
if [[ "$TFCI_NIGHTLY_UPDATE_VERSION_ENABLE" == 1 ]]; then
  tfrun python3 tensorflow/tools/ci_build/update_version.py --nightly
fi
source ci/official/utilities/get_versions.sh

# Note on gsutil commands:

> Requests, tüm zamanların en çok indirilen Python  <abbr title="Paket: Package">paketlerinden</abbr> biridir.

Kullanım şekli oldukça basit. Örneğin bir `GET` isteği yapmak için aşağıdaki yeterli:

```Python
response = requests.get("http://example.com/some/url")
```

Bunun FastAPI'deki API <abbr title="Yol İşlemi: Path Operation">*yol işlemi*</abbr> şöyle görünür:

```Python hl_lines="1"
@app.get("/some/url")
def read_url():

Sonuçları vermeden önce beklemeyi gerektirecek ve yeni Python özelliklerini destekleyen bir işlem olduğunda aşağıdaki gibi kodlayabilirsiniz:

```Python
burgers = await get_burgers(2)
```

build:release_linux_base --linkopt=-Wl,--undefined-version

# Container environment settings below this point.
# Use Python 3.X as installed in container image
build:release_linux_base --action_env PYTHON_BIN_PATH="/usr/bin/python3"
build:release_linux_base --action_env PYTHON_LIB_PATH="/usr/lib/tf_python"
build:release_linux_base --python_path="/usr/bin/python3"
# Set Clang as compiler. Use the actual path to clang installed in container.

요약하면, 여러분은 매개변수의 타입, 본문 등을 함수 매개변수로서 **한번에** 선언했습니다.

여러분은 현대 표준 파이썬 타입으로 이를 행했습니다.

새로운 문법, 특정 라이브러리의 메소드나 클래스 등을 배울 필요가 없습니다.

그저 표준 **Python** 입니다.

예를 들어, `int`에 대해선:

```Python
item_id: int
```

또는 좀 더 복잡한 `Item` 모델에 대해선:

```Python
item: Item
```

...그리고 단 하나의 선언으로 여러분이 얻는 것은:

* 다음을 포함한 편집기 지원:
    * 자동완성.
    * 타입 검사.
* 데이터 검증:

///

Dem `status_code`-Parameter wird eine Zahl mit dem HTTP-Statuscode übergeben.

/// info

Alternativ kann `status_code` auch ein `IntEnum` erhalten, so wie Pythons <a href="https://docs.python.org/3/library/http.html#http.HTTPStatus" class="external-link" target="_blank">`http.HTTPStatus`</a>.

///

Das wird:

* Diesen Statuscode mit der Response zurücksenden.
