따라서, `User_Agent` 등과 같이 첫 문자를 대문자화할 필요없이 파이썬 코드에서처럼 `user_agent`로 사용합니다.

만약 언더스코어를 하이픈으로 자동 변환을 비활성화해야 할 어떤 이유가 있다면, `Header`의 `convert_underscores` 매개변수를 `False`로 설정하십시오:

```Python hl_lines="10"
{!../../docs_src/header_params/tutorial002.py!}
```

/// warning | "경고"

`convert_underscore`를 `False`로 설정하기 전에, 어떤 HTTP 프록시들과 서버들은 언더스코어가 포함된 헤더 사용을 허락하지 않는다는 것을 명심하십시오.

## 중복 헤더

중복 헤더들을 수신할 수 있습니다. 즉, 다중값을 갖는 동일한 헤더를 뜻합니다.
