## 검증 추가

매개변수 `min_length` 또한 추가할 수 있습니다:

```Python hl_lines="9"
{!../../docs_src/query_params_str_validations/tutorial003.py!}
```

## 정규식 추가

매개변수와 일치해야 하는 <abbr title="정규표현식(regular expression), regex 또는 regexp는 문자열 조회 패턴을 정의하는 문자들의 순열입니다">정규표현식</abbr>을 정의할 수 있습니다:

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

이 특정 정규표현식은 전달 받은 매개변수 값을 검사합니다:
