# Variables de Entorno

/// tip | Consejo

Si ya sabes qué son las "variables de entorno" y cómo usarlas, siéntete libre de saltarte esto.

///

Una variable de entorno (también conocida como "**env var**") es una variable que vive **fuera** del código de Python, en el **sistema operativo**, y podría ser leída por tu código de Python (o por otros programas también).

 * imposes both obligations and limits on the client application.
 *
 * ### The response body must be closed.
 *
 * Each response body is backed by a limited resource like a socket (live network responses) or
 * an open file (for cached responses). Failing to close the response body will leak resources and
 * may ultimately cause the application to slow down or crash.

/// tip

Mỗi khi bạn cài đặt thêm một **package mới** trong môi trường đó, hãy **kích hoạt** môi trường đó lại.

Điều này đảm bảo rằng khi bạn sử dụng một **chương trình dòng lệnh (<abbr title="command line interface">CLI</abbr>)** được cài đặt từ gói đó, bạn sẽ dùng bản cài đặt từ môi trường ảo của mình thay vì bản được cài đặt toàn cục khác có thể có phiên bản khác với phiên bản bạn cần.
