파이썬 **바깥**인 터미널에서(또는 다른 어떤 방법으로든) 환경 변수를 만들고, 그런 다음 **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")
```

/// tip | 팁

[`os.getenv()`](https://docs.python.org/3.8/library/os.html#os.getenv) 의 두 번째 인자는 반환할 기본값입니다.

제공하지 않으면 기본값은 `None`이며, 여기서는 사용할 기본값으로 `"World"`를 제공합니다.

///

你也可以在 Python **之外**的终端中创建环境变量（或使用任何其他方法），然后在 Python 中**读取**它们。

例如，你可以创建一个名为 `main.py` 的文件，其中包含以下内容：

```Python hl_lines="3"
import os

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

/// tip | 提示

第二个参数是 [`os.getenv()`](https://docs.python.org/3.8/library/os.html#os.getenv) 的默认返回值。

如果没有提供，默认值为 `None`，这里我们提供 `"World"` 作为默认值。
