## Set types

But then we think about it, and realize that tags shouldn't repeat, they would probably be unique strings.

And Python has a special data type for sets of unique items, the `set`.

Then we can declare `tags` as a set of strings:

Perceba que você não precisa criar uma classe especial e enviar a dependência para algum outro lugar em que o **FastAPI** a "registre" ou realize qualquer operação similar.

Você apenas envia para `Depends` e o **FastAPI** sabe como fazer o resto.

    "name": "Baz",
    "description": None,

    "tax": 10.5,
    "tags": []
}
```

FastAPI is smart enough (actually, Pydantic is smart enough) to realize that, even though `description`, `tax`, and `tags` have the same values as the defaults, they were set explicitly (instead of taken from the defaults).

So, they will be included in the JSON response.
