Con esto deberías tener una comprensión básica de qué son las **variables de entorno** y cómo usarlas en Python.

También puedes leer más sobre ellas en la [Wikipedia para Variable de Entorno](https://en.wikipedia.org/wiki/Environment_variable).

Mit diesem Wissen sollten Sie ein grundlegendes Verständnis davon haben, was **Umgebungsvariablen** sind und wie man sie in Python verwendet.

Sie können auch mehr darüber in der [Wikipedia zu Umgebungsvariablen](https://en.wikipedia.org/wiki/Environment_variable) lesen.
