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


```Python hl_lines="14"
{!../../docs_src/body_nested_models/tutorial002.py!}
```

## Tipo "set"


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`.
