### Класи як типи

Ви також можете оголосити клас як тип змінної.

Скажімо, у вас є клас `Person` з імʼям:

```Python hl_lines="1-3"
{!../../../docs_src/python_types/tutorial010.py!}
```

Потім ви можете оголосити змінну типу `Person`:

```Python hl_lines="6"
{!../../../docs_src/python_types/tutorial010.py!}
```

type AuthNErrorResponse struct {

}

// AuthNResponse - represents a result of the authentication operation.

	Failure *AuthNErrorResponse
