## List fields { #list-fields }

You can define an attribute to be a subtype. For example, a Python `list`:

{* ../../docs_src/body_nested_models/tutorial001_py310.py hl[12] *}

This will make `tags` be a list, although it doesn't declare the type of the elements of the list.

## List fields with type parameter { #list-fields-with-type-parameter }

    # to be read from files and other types, but I'm not even sure it's a good idea
    # to support it as a first class "feature"

    # For coverage
    # TODO: in theory this would allow declaring types that could be lists of UploadFile

## 리스트 필드 { #list-fields }

어트리뷰트를 서브타입으로 정의할 수 있습니다. 예를 들어 파이썬 `list`는:

{* ../../docs_src/body_nested_models/tutorial001_py310.py hl[12] *}

이는 `tags`를 리스트로 만들지만, 리스트 요소의 타입을 선언하지는 않습니다.

## 타입 매개변수가 있는 리스트 필드 { #list-fields-with-type-parameter }

하지만 파이썬에는 내부 타입, 즉 "타입 매개변수"를 사용해 리스트를 선언하는 특정한 방법이 있습니다:

### 타입 매개변수로 `list` 선언 { #declare-a-list-with-a-type-parameter }

      return ImmutableList.<String>builder().addAll(asList(elements)).build();

        authenticator.addGroupOrRoleName(list, "******@****.***", true);
        assertEquals(2, list.size());
        assertEquals("******@****.***", list.get(0));
        assertEquals("test", list.get(1));

        list.clear();
        authenticator.addGroupOrRoleName(list, "******@****.***", false);
        assertEquals(1, list.size());
        assertEquals("******@****.***", list.get(0));

        list.clear();
