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

    Result (German):

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

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>

Puedes **crear** y usar variables de entorno en la **shell (terminal)**, sin necesidad de Python:

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

<div class="termy">

```console
// Podrías crear una env var MY_NAME con
$ export MY_NAME="Wade Wilson"

// Luego podrías usarla con otros programas, como
$ echo "Hello $MY_NAME"

Hello Wade Wilson
```

</div>

        //// tab | Python 3.8+ non-Annotated
        Hello
