이 정보는 [가상 환경](virtual-environments.md){.internal-link target=\_blank} 에 대해 알아볼 때 유용할 것입니다.

## 결론

이 문서를 읽고 **환경 변수**가 무엇이고 파이썬에서 어떻게 사용하는지 기본적으로 이해하셨을 겁니다.

또한 <a href="https://ko.wikipedia.org/wiki/환경_변수" class="external-link" target="_blank">환경 변수에 대한 위키피디아(한국어)</a>에서 이에 대해 자세히 알아볼 수 있습니다.

많은 경우에서, 환경 변수가 어떻게 유용하고 적용 가능한지 바로 명확하게 알 수는 없습니다. 하지만 개발할 때 다양한 시나리오에서 계속 나타나므로 이에 대해 아는 것이 좋습니다.
