## Special types and validation { #special-types-and-validation }

Apart from normal singular types like `str`, `int`, `float`, etc. you can use more complex singular types that inherit from `str`.

### Объявление `list` с указанием типов для вложенных элементов

Объявление типов для элементов (внутренних типов) вложенных в такие типы как `list`, `dict`, `tuple`:

* Если у вас Python версии ниже чем 3.9, импортируйте их аналог из модуля `typing`
* Передайте внутренний(ие) тип(ы) как "параметры типа", используя квадратные скобки: `[` и `]`

В Python версии 3.9 это будет выглядеть так:

    Interceptors that rewrite or replace the request body may now inadvertently interfere with
    duplex request bodies. Such interceptors should check `RequestBody.isDuplex()` and avoid
    accessing the request body when it is.

    Duplex calls require HTTP/2. If HTTP/1 is established instead the duplex call will fail. The
    most common use of duplex calls is [gRPC][grpc_http2].

Parametreler bağlantının bir parçası oldukları için doğal olarak string olarak değerlendirilirler.
