python实现 tcp通讯之列表收发 socket发“二进制信息帧”

众所周知，tcp通过socket实现的通讯，但是对于日常使用的列表收发就显得有些困难了，在这期间，我看过很多文章，已经开始头大了，此时看到一篇文章里讲了python中的bytes和bytearray类型的数据与转码，我就看到了希望：
文章链接：http://cnblogs.com/f-ck-need-u/p/10185965.html
从其中我看到了关于列表转化为bytearray和bytearray转化为列表的操作，

nn = bytearray([10,11,12])

x = [i for i in nn]
print(x)

这就OK了，通过这样的方式可以将列表转化为bytearray转发出去

client代码：

import socket
import threading
import time

class socketCreateStoppable(threading.Thread):
    """Thread class with a stop() method. The thread itself has to check
    regularly for the stopped() condition."""

    def __init__(self,server_ip, server_port):
        super(socketCreateStoppable, self).__init__()
        self._stop_event = threading.Event()
        #print('server_ip',server_ip_list)
        #print(time.localtime(time.time()))
        self.server_ip = server_ip
        self.server_port = server_port
        self.tcp_client = socket.socket(family=socket.AF_INET, type=socket.SOCK_STREAM)


    def stop(self):
        print(time.time())
        print('#'*20)
        self._stop_event.set()
        self.tcp_client.close()   # 在停止的时候将tcp_client关掉
        print(time.time(),'stop success')

    def stopped(self):
        return self._stop_event.is_set()

    def run(self):
        while True:
            try:
                self.tcp_client.connect((self.server_ip, self.server_port))
                print('server_ip:', self.server_ip)
                while True:
                    # 3.收发
                    recv_content = self.tcp_client.recv(1024)
                    print(type(recv_content))
                    self.dataList = list(recv_content)
                    print(self.dataList)
            except Exception as e:
                print(e)
                time.sleep(5)
            #print("sleep 1s")
            time.sleep(1)
            if self.stopped():
                # 做一些必要的收尾工作
                self.tcp_client.close()
                break

            print(client_addr)
            while True:
                x = [1,2,3]
                send_cont = bytearray(x)
                new_server_socket.send(send_cont)
                time.sleep(2)
