Sie können Umgebungsvariablen in der **Shell (Terminal)** erstellen und verwenden, ohne Python zu benötigen:

//// tab | Linux, macOS, Windows Bash

<div class="termy">

```console
// Sie können eine Umgebungsvariable MY_NAME erstellen mit
$ export MY_NAME="Wade Wilson"

// Dann können Sie sie mit anderen Programmen verwenden, etwa
$ echo "Hello $MY_NAME"

Hello Wade Wilson
```

</div>

////

Examples:

    Source (English):

        «««
        "Hello world"
        “Hello Universe”
        "He said: 'Hello'"
        “my name is ‘Nils’”
        `"__main__"`
        `"items"`
        »»»

    Result (German):

        «««
        „Hallo Welt“
        „Hallo Universum“
        „Er sagte: ‚Hallo‘“
        „Mein Name ist ‚Nils‘“
        `"__main__"`
        `"items"`

You can **create** and use environment variables in the **shell (terminal)**, without needing Python:

//// tab | Linux, macOS, Windows Bash

<div class="termy">

```console
// You could create an env var MY_NAME with
$ export MY_NAME="Wade Wilson"

// Then you could use it with other programs, like
$ echo "Hello $MY_NAME"

Hello Wade Wilson
```

</div>

////

$ $Env:MY_NAME = "Wade Wilson"

// 在其他程序中使用它，例如
$ echo "Hello $Env:MY_NAME"

Hello Wade Wilson
```

</div>

////

## 在 Python 中读取环境变量

你也可以在 Python **之外**的终端中创建环境变量（或使用任何其他方法），然后在 Python 中**读取**它们。

例如，你可以创建一个名为 `main.py` 的文件，其中包含以下内容：

```Python hl_lines="3"
import os

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

/// tip

Você pode **criar** e usar variáveis de ambiente no **shell (terminal)**, sem precisar do Python:

//// tab | Linux, macOS, Windows Bash

<div class="termy">

```console
// Você pode criar uma variável de ambiente MY_NAME com
$ export MY_NAME="Wade Wilson"

// Então você pode usá-la com outros programas, como
$ echo "Hello $MY_NAME"

Hello Wade Wilson
```

</div>
