## 검증 추가

매개변수 `min_length` 또한 추가할 수 있습니다:

{* ../../docs_src/query_params_str_validations/tutorial003.py hl[9] *}

## 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:

{* ../../docs_src/query_params_str_validations/tutorial004.py hl[10] *}

이 특정 정규표현식은 전달 받은 매개변수 값을 검사합니다:

* `^`: 이전에 문자가 없고 뒤따르는 문자로 시작합니다.

// text, stripped of any trailing end-of-line marker. The returned line may
// be empty. The end-of-line marker is one optional carriage return followed
// by one mandatory newline. In regular expression notation, it is `\r?\n`.
// The last non-empty line of input will be returned even if it has no
// newline.
