### Классы как типы

Вы также можете объявить класс как тип переменной.

Допустим, у вас есть класс `Person` с полем `name`:

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

Тогда вы можете объявить переменную типа `Person`:

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

```Python
images: List[Image]
```

oder in Python 3.9 und darüber:

```Python
images: list[Image]
```

so wie in:

problems. If your service has multiple IP addresses, OkHttp will attempt alternate addresses if the
first connect fails. This is necessary for IPv4+IPv6 and services hosted in redundant data
centers. OkHttp supports modern TLS features (TLS 1.3, ALPN, certificate pinning). It can be
configured to fall back for broad connectivity.

Using OkHttp is easy. Its request/response API is designed with fluent builders and immutability. It
