Первый параметр типа — для ключей `dict`.

Второй параметр типа — для значений `dict`:

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

Это означает:

* Переменная `prices` — это `dict`:
    * Ключи этого `dict` имеют тип `str` (скажем, название каждой позиции).
    * Значения этого `dict` имеют тип `float` (скажем, цена каждой позиции).

Der erste Typ-Parameter ist für die Schlüssel des `dict`.

Der zweite Typ-Parameter ist für die Werte des `dict`:

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

Das bedeutet:

* Die Variable `prices` ist ein `dict`:
    * Die Schlüssel dieses `dict` sind vom Typ `str` (z. B. die Namen der einzelnen Artikel).
    * Die Werte dieses `dict` sind vom Typ `float` (z. B. der Preis jedes Artikels).

### Criar com `HeroCreate` e retornar um `HeroPublic` { #create-with-herocreate-and-return-a-heropublic }

Agora que temos **múltiplos modelos**, podemos atualizar as partes do app que os utilizam.

Recebemos na requisição um *modelo de dados* `HeroCreate`, e a partir dele, criamos um *modelo de tabela* `Hero`.
