## Campos do tipo Lista { #list-fields }

Você pode definir um atributo como um subtipo. Por exemplo, uma `list` do Python:

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

Isso fará com que tags seja uma lista de itens mesmo sem declarar o tipo dos elementos desta lista.

## Campos do tipo Lista com um parâmetro de tipo { #list-fields-with-type-parameter }
