매개변수들은 이름으로 감지됩니다:

```Python hl_lines="8  10"
{!../../docs_src/query_params/tutorial004.py!}
```

## 필수 쿼리 매개변수

경로가 아닌 매개변수에 대한 기본값을 선언할 때(지금은 쿼리 매개변수만 보았습니다), 해당 매개변수는 필수적(Required)이지 않았습니다.

특정값을 추가하지 않고 선택적으로 만들기 위해선 기본값을 `None`으로 설정하면 됩니다.

그러나 쿼리 매개변수를 필수로 만들려면 단순히 기본값을 선언하지 않으면 됩니다:

```Python hl_lines="6-7"
{!../../docs_src/query_params/tutorial005.py!}
```
