우리 역시 이제부터 메소드를 "**작동**"이라고 부를 것입니다.

#### *경로 작동 데코레이터* 정의

```Python hl_lines="6"
{!../../docs_src/first_steps/tutorial001.py!}
```

`@app.get("/")`은 **FastAPI**에게 바로 아래에 있는 함수가 다음으로 이동하는 요청을 처리한다는 것을 알려줍니다.

* 경로 `/`
* <abbr title="HTTP GET 메소드"><code>get</code> 작동</abbr> 사용

/// info | "`@decorator` 정보"

이 `@something` 문법은 파이썬에서 "데코레이터"라 부릅니다.
