例えば、以下のような`main.py`ファイルを用意します:

```Python hl_lines="3"
import os

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

/// tip

<a href="https://docs.python.org/3.8/library/os.html#os.getenv" class="external-link" target="_blank">`os.getenv()`</a> の第2引数は、デフォルトで返される値を指定します。

この引数を省略するとデフォルト値として`None`が返されますが、ここではデフォルト値として`"World"`を指定しています。

///

次に、このPythonプログラムを呼び出します。

## Pydantic 기능

**FastAPI**는 <a href="https://docs.pydantic.dev/" class="external-link" target="_blank"><strong>Pydantic</strong></a>을 기반으로 하며 Pydantic과 완벽하게 호환됩니다. 그래서 어느 추가적인 Pydantic 코드를 여러분이 가지고 있든 작동할 것입니다.
