    Oder, wenn Sie Bash für Windows verwenden (z. B. <a href="https://gitforwindows.org/" class="external-link" target="_blank">Git Bash</a>):

    <div class="termy">

    ```console
    $ source ./env/Scripts/activate
    ```

    </div>

Um zu überprüfen, ob es funktioniert hat, geben Sie ein:

=== "Linux, macOS, Windows Bash"

Hello Wade Wilson from Python
```

</div>

Da Umgebungsvariablen außerhalb des Codes festgelegt, aber vom Code gelesen werden können und nicht zusammen mit den übrigen Dateien gespeichert (an `git` committet) werden müssen, werden sie häufig für Konfigurationen oder Einstellungen verwendet.

    ```console
    $ .\env\Scripts\Activate.ps1
    ```

    </div>

=== "Windows Bash"

    Or if you use Bash for Windows (e.g. <a href="https://gitforwindows.org/" class="external-link" target="_blank">Git Bash</a>):

    <div class="termy">

    ```console
    $ source ./env/Scripts/activate
    ```

    </div>

要检查操作是否成功，运行：

=== "Linux, macOS, Windows Bash"

    <div class="termy">

// Now it can read the environment variable

Hello Wade Wilson from Python
```

</div>

As environment variables can be set outside of the code, but can be read by the code, and don't have to be stored (committed to `git`) with the rest of the files, it's common to use them for configurations or settings.

You can also create an environment variable only for a specific program invocation, that is only available to that program, and only for its duration.

// 但是如果我们先创建一个环境变量
$ export MY_NAME="Wade Wilson"

// 然后再次调用程序
$ python main.py

// 现在它可以读取环境变量

Hello Wade Wilson from Python
```

</div>

由于环境变量可以在代码之外设置，但可以由代码读取，并且不需要与其他文件一起存储（提交到 `git`），因此通常将它们用于配置或设置。



您还可以仅为特定程序调用创建一个环境变量，该环境变量仅对该程序可用，并且仅在其运行期间有效。

要做到这一点，在程序本身之前的同一行创建它：

<div class="termy">

```console
// 在此程序调用行中创建一个名为 MY_NAME 的环境变量
