Now, for FastAPI, it will see the return type and make sure that what you return includes **only** the fields that are declared in the type.

FastAPI does several things internally with Pydantic to make sure that those same rules of class inheritance are not used for the returned data filtering, otherwise you could end up returning much more data than what you expected.

The first type parameter is for the keys of the `dict`.

The second type parameter is for the values of the `dict`:

{* ../../docs_src/python_types/tutorial008_py39.py hl[1] *}

This means:

* The variable `prices` is a `dict`:
    * The keys of this `dict` are of type `str` (let's say, the name of each item).
    * The values of this `dict` are of type `float` (let's say, the price of each item).

#### Union { #union }

O segundo parâmetro de tipo é para os valores do `dict`:

{* ../../docs_src/python_types/tutorial008_py39.py hl[1] *}

Isso significa que:

* A variável `prices` é um `dict`:
    * As chaves deste `dict` são do tipo `str` (digamos, o nome de cada item).
    * Os valores deste `dict` são do tipo `float` (digamos, o preço de cada item).
