Você declara a dependência como o tipo do parâmetro, e utiliza `Depends()` sem nenhum parâmetro, em vez de ter que escrever a classe *novamente* dentro de `Depends(CommonQueryParams)`.

O mesmo exemplo ficaria então dessa forma:

{* ../../docs_src/dependencies/tutorial004_an_py310.py hl[19] *}

...e o **FastAPI** saberá o que fazer.

/// tip | Dica

 * which is commonly used for Kerberos-based authentication in Windows environments.
 * It handles the negotiation between client and server to establish a secure
 * authentication context without requiring users to explicitly enter credentials.
 *
 * The authenticator supports various configuration options including delegation,
 * basic authentication fallback, and localhost authentication bypass.

Cuando instalas FastAPI, viene con un servidor de producción, Uvicorn, y puedes iniciarlo con el comando `fastapi run`.

Pero también puedes instalar un servidor ASGI manualmente.

Asegúrate de crear un [entorno virtual](../virtual-environments.md), actívalo, y luego puedes instalar la aplicación del servidor.

Por ejemplo, para instalar Uvicorn:

<div class="termy">

```console
$ pip install "uvicorn[standard]"

{* ../../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`.

Então podemos declarar `tags` como um conjunto de strings:

{* ../../docs_src/body_nested_models/tutorial003_py310.py hl[12] *}

            this.setStartDate(start);
            this.setEndDate(end);
            this.updateView();
        },

        keydown: function(e) {
            //hide on tab or enter
            if ((e.keyCode === 9) || (e.keyCode === 13)) {
                this.hide();
            }

            //hide on esc and prevent propagation
            if (e.keyCode === 27) {
