请使用python实现一个服务器-客户端程序服务端监听5555的tcp端口当收到客户端发来的握手包后构造一个速率为1000bps且内容为全0的数据流以udp协议向客户端的6666端口持续发送客服端的ip地址由服务器收到的握手包中获取。请实现上面的服务端和客户端

服务端代码：

import socket

SERVER_PORT = 5555
UDP_RATE = 1000
UDP_DATA = b'\x00' * 1024


def main():
    # 创建tcp socket
    server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    server_socket.bind(('0.0.0.0', SERVER_PORT))
    server_socket.listen()

    print('Server started, listening on port', SERVER_PORT)

    # 等待客户端连接
    client_socket, client_address = server_socket.accept()
    print('Client connected:', client_address)

    # 接收握手包
    handshake_data = client_socket.recv(1024)
    print('Received handshake data:', handshake_data)

    # 解析握手包获取客户端ip和端口号
    client_ip = handshake_data.split(b':')[0]
    client_port = int(handshake_data.split(b':')[1])

    # 创建udp socket
    udp_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

    # 持续发送数据流
    while True:
        udp_socket.sendto(UDP_DATA, (client_ip, client_port))
        time.sleep(1/UDP_RATE)


if __name__ == '__main__':
    main()

客户端代码：

import socket

SERVER_ADDRESS = '127.0.0.1'
SERVER_PORT = 5555
CLIENT_PORT = 6666
HANDSHAKE_DATA = b'Hello server!'


def main():
    # 创建tcp socket
    client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    client_socket.connect((SERVER_ADDRESS, SERVER_PORT))

    # 发送握手包
    client_socket.send(HANDSHAKE_DATA)

    # 创建udp socket
    udp_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    udp_socket.bind(('0.0.0.0', CLIENT_PORT))

    # 接收数据流
    while True:
        data, server_address = udp_socket.recvfrom(1024)
        print('Received data from server:', data)


if __name__ == '__main__':
    main()
