                            },

So, in our example, we can make `tags` be specifically a "list of strings":

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

## Set types { #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:

        }

        @Override
        public boolean onJavadocTag(String tag, String value) {
            listener.warning(String.format("Unsupported Javadoc tag '%s'", tag));
            Element element = document.createElement("UNHANDLED-TAG");
            element.appendChild(document.createTextNode(String.format("{@%s %s}", tag, value)));
            nodes.appendChild(element);
            return true;
        }
    }

    name: str
    description: str | None = None
    price: float
    tax: float = 10.5
    tags: list[str] = []


items = {
    "foo": {"name": "Foo", "price": 50.2},
    "bar": {"name": "Bar", "description": "The bartenders", "price": 62, "tax": 20.2},
    "baz": {"name": "Baz", "description": None, "price": 50.2, "tax": 10.5, "tags": []},
}
