如何在两个UDP客户端之间发送消息？

import socket

# 创建UDP套接字
sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

# 目标地址和端口
server_address = ('localhost', 10000)

try:
    # 发送消息
    message = b'Hello, UDP Client B!'
    print(f'Sending: {message}')
    sent = sock.sendto(message, server_address)

    # 接收响应
    data, server = sock.recvfrom(4096)
    print(f'Received: {data}')

finally:
    sock.close()

import socket

# 创建UDP套接字
sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

# 绑定地址和端口
server_address = ('localhost', 10000)
sock.bind(server_address)

try:
    while True:
        # 接收消息
        data, address = sock.recvfrom(4096)
        print(f'Received: {data} from {address}')

        # 发送响应
        message = b'Hello back, UDP Client A!'
        print(f'Sending: {message}')
        sock.sendto(message, address)

finally:
    sock.close()
