In the previous example, because the classes were different, we had to use the `response_model` parameter. But that also means that we don't get the support from the editor and tools checking the function return type.

But in most of the cases where we need to do something like this, we want the model just to **filter/remove** some of the data as in this example.

No exemplo anterior, como as classes eram diferentes, tivemos que usar o parâmetro `response_model`. Mas isso também significa que não temos suporte do editor e das ferramentas verificando o tipo de retorno da função.

Mas na maioria dos casos em que precisamos fazer algo assim, queremos que o modelo apenas **filtre/remova** alguns dados como neste exemplo.

### Classes as types { #classes-as-types }

You can also declare a class as the type of a variable.

Let's say you have a class `Person`, with a name:
