하지만 기본적으로 모든 것이 "그냥 작동합니다".

### 검증

* 다음을 포함한, 대부분의 (혹은 모든?) 파이썬 **데이터 타입** 검증할 수 있습니다:
    * JSON 객체 (`dict`).
    * 아이템 타입을 정의하는 JSON 배열 (`list`).
    * 최소 길이와 최대 길이를 정의하는 문자열 (`str`) 필드.
    * 최솟값과 최댓값을 가지는 숫자 (`int`, `float`), 그 외.

* 다음과 같이 더욱 이색적인 타입에 대해 검증할 수 있습니다:
    * URL.
    * 이메일.
    * UUID.
    * ...다른 것들.

<p>
It is impractical to list all the instructions and other details for each machine.
To see what instructions are defined for a given machine, say ARM,
look in the source for the <code>obj</code> support library for
that architecture, located in the directory <code>src/cmd/internal/obj/arm</code>.
In that directory is a file <code>a.out.go</code>; it contains
a long list of constants starting with <code>A</code>, like this:

            <tag>
              <name>spec</name>
              <placement>X</placement>
            </tag>
          </tags>

          <!-- TODO(cpovirk): Move this to the parent after making the package-list files available there. -->
          <!-- We add the link ourselves so that we can choose Java 25 over the version that -source suggests. -->

O app acima é um exemplo mínimo e simples para demonstrar como lidar e transmitir mensagens para várias conexões WebSocket.

Mas tenha em mente que, como tudo é manipulado na memória, em uma única list, ele só funcionará enquanto o processo estiver em execução e só funcionará com um único processo.
