## Criar e Usar Variáveis de Ambiente { #create-and-use-env-vars }

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"
