Por exemplo, o modelo acima declara um JSON "`object`" (ou `dict` no Python) como esse:

```JSON
{

    "description": "Uma descrição opcional",
    "price": 45.2,
    "tax": 3.5
}

...como `description` e `tax` são opcionais (Com um valor padrão de `None`), esse JSON "`object`" também é válido:

Модель ответа, гарантирующая наличие поля со значением типа `int` (не `None`), очень полезна при разработке API клиентов. Определенность в передаваемых данных может обеспечить написание более простого кода.

    line = log_lines[i]
    result_store_line_match = re.search(RESULT_STORE_LINK_RE, line)
