## 파이썬에서 환경 변수 읽기

파이썬 **바깥**인 터미널에서(다른 도구로도 가능) 환경 변수를 생성도 할 수도 있고, 이를 **파이썬에서 읽을 수 있습니다.**

예를 들어 다음과 같은 `main.py` 파일이 있다고 합시다:

```Python hl_lines="3"
import os

name = os.getenv("MY_NAME", "World")
print(f"Hello {name} from Python")
```

<a href="https://docs.python.org/3.8/library/os.html#os.getenv" class="external-link" target="_blank">`os.getenv()`</a> 의 두 번째 인자는 반환할 기본값입니다.

- The names of ResourceClaims generated from ResourceClaimTemplate are now generated. The base name is still `<pod>-<claim name>`, but a random suffix will avoid name collisions.
