Но так мы сможем сосредоточиться на том, как работает система **Dependency Injection**.

### Создайте зависимость, или «dependable» (от чего что-то зависит) { #create-a-dependency-or-dependable }

Сначала сосредоточимся на зависимости.

Это просто функция, которая может принимать те же параметры, что и *функция обработки пути*:

### Создание класса `Enum` { #create-an-enum-class }

Импортируйте `Enum` и создайте подкласс, который наследуется от `str` и `Enum`.

Мы наследуемся от `str`, чтобы документация API могла понять, что значения должны быть типа `string` и отображалась правильно.

## Importe o `BaseModel` do Pydantic { #import-pydantics-basemodel }

Primeiro, você precisa importar `BaseModel` do `pydantic`:

{* ../../docs_src/body/tutorial001_py310.py hl[2] *}

## Crie seu modelo de dados { #create-your-data-model }

Então você declara seu modelo de dados como uma classe que herda `BaseModel`.

Utilize os tipos Python padrão para todos os atributos:

{* ../../docs_src/body/tutorial001_py310.py hl[5:9] *}
