## 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")
```

        // Verify that the cause is correctly set
        assertNotNull(runtimeException);
        assertEquals(servletException, runtimeException.getCause());

        // Verify the message contains the exception class name
        assertTrue(runtimeException.getMessage().contains(ServletException.class.getName()));
    }

    public void test_instanceOfRuntimeException() {
        // Create and wrap a ServletException

}

// Check if the given error corresponds to ENOTDIR (is not a directory).
func isSysErrNotDir(err error) bool {
	return errors.Is(err, syscall.ENOTDIR)
}

// Check if the given error corresponds to the ENAMETOOLONG (name too long).
func isSysErrTooLong(err error) bool {
	return errors.Is(err, syscall.ENAMETOOLONG)
}

// Check if the given error corresponds to the ELOOP (too many symlinks).
func isSysErrTooManySymlinks(err error) bool {
