Eine Umgebungsvariable (auch bekannt als „**env var**“) ist eine Variable, die **außerhalb** des Python-Codes im **Betriebssystem** lebt und von Ihrem Python-Code (oder auch von anderen Programmen) gelesen werden kann.

Umgebungsvariablen können nützlich sein, um **Einstellungen** der Anwendung zu handhaben, als Teil der **Installation** von Python usw.

## Umgebungsvariablen erstellen und verwenden { #create-and-use-env-vars }

Переменная окружения (также известная как «**env var**») - это переменная, которая живет **вне** кода Python, в **операционной системе**, и может быть прочитана вашим кодом Python (или другими программами).

Переменные окружения могут быть полезны для работы с **настройками** приложений, как часть **установки** Python и т.д.

  implementation of the BasicComponentConfigurator. This ExpressionEvaluator
  simply returns the expression itself as the resolved value, which adds
  very little value to the container. Things like ${project.build.resources}
  are not resolved, and result in a type mismatch for the member injection.

  We need a replacement for DefaultExpressionEvaluator that is capable of
