Portanto, em nosso exemplo, podemos fazer com que `tags` sejam especificamente uma "lista de strings":

{* ../../docs_src/body_nested_models/tutorial002_py310.py hl[12] *}

## Tipos "set" { #set-types }

Mas então, quando nós pensamos mais, percebemos que as tags não devem se repetir, elas provavelmente devem ser strings únicas.

E que o Python tem um tipo de dados especial para conjuntos de itens únicos, o `set`.
