> Requests is one of the most downloaded Python packages of all time

사용 방법은 매우 간단합니다. 예를 들어 `GET` 요청을 하려면 다음처럼 작성합니다:

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

이에 대응하는 FastAPI의 API *경로 처리*는 다음과 같이 보일 수 있습니다:

```Python hl_lines="1"
@app.get("/some/url")
def read_url():
    return {"message": "Hello World"}
```

# BEGIN TF TEST SUITE OPTIONS
# These are convenience config options that effectively declare TF's CI test suites. Look
# at the scripts of ci/official/ to see how TF's CI uses them.

# PYTHON TESTS run a suite of Python tests intended for verifying that the Python wheel
# will work properly. These are usually run Nightly or upon Release.
# CPU WHEEL

## `async` and `await` { #async-and-await }

Modern versions of Python have a very intuitive way to define asynchronous code. This makes it look just like normal "sequential" code and do the "awaiting" for you at the right moments.

When there is an operation that will require waiting before giving the results and has support for these new Python features, you can code it like:

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

        map sigbuild-r2.12-clang-python3.10 2.12-python3.10
        map sigbuild-r2.12-clang-python3.11 2.12-python3.11
        # TF 2.13
        map sigbuild-r2.13 2.13-python3.9
        map sigbuild-r2.13-python3.8 2.13-python3.8
        map sigbuild-r2.13-python3.9 2.13-python3.9
        map sigbuild-r2.13-python3.10 2.13-python3.10
        map sigbuild-r2.13-python3.11 2.13-python3.11

## Ler Variáveis de Ambiente no Python { #read-env-vars-in-python }

Você também pode criar variáveis de ambiente **fora** do Python, no terminal (ou com qualquer outro método) e depois **lê-las no Python**.

Por exemplo, você poderia ter um arquivo `main.py` com:

```Python hl_lines="3"
import os

name = os.getenv("MY_NAME", "World")
print(f"Hello {name} from Python")
```

/// tip | Dica

Beachten Sie, wie wir `CommonQueryParams` im obigen Code zweimal schreiben:

//// tab | Python 3.10+

```Python
commons: Annotated[CommonQueryParams, Depends(CommonQueryParams)]
```

////

//// tab | Python 3.10+ nicht annotiert

/// tip | Tipp

Bevorzugen Sie die `Annotated`-Version, falls möglich.

///

```Python
commons: CommonQueryParams = Depends(CommonQueryParams)
```

Hello Wade Wilson

## 在 Python 中讀取環境變數 { #read-env-vars-in-python }

你也可以在 Python **之外**的終端機中建立環境變數（或使用其他方法），然後在 Python 中**讀取**它們。

例如，你可以建立一個名為 `main.py` 的檔案，其中包含以下內容：

```Python hl_lines="3"
import os

name = os.getenv("MY_NAME", "World")
print(f"Hello {name} from Python")
```

/// tip

第二個參數是 [`os.getenv()`](https://docs.python.org/3.8/library/os.html#os.getenv) 的預設回傳值。

<div class="termy">

```console
$ python -m venv .venv
```

</div>

/// details | Що означає ця команда

* `python`: використати програму з назвою `python`
* `-m`: викликати модуль як скрипт, далі ми вкажемо, який модуль
* `venv`: використати модуль з назвою `venv`, який зазвичай уже встановлено з Python

<div class="termy">

```console
$ which python

/home/user/code/awesome-project/.venv/bin/python
```

</div>

Si muestra el binario de `python` en `.venv/bin/python`, dentro de tu proyecto (en este caso `awesome-project`), entonces funcionó. 🎉
