Python 3-如何使用socket创建一个简单的聊天程序？

import socket
import threading

def receive_message(client_socket):
    while True:
        try:
            message = client_socket.recv(1024).decode('utf-8')
            print(message)
        except:
            # 发生异常时，说明连接已断开，退出循环
            break

def send_message(client_socket):
    while True:
        message = input()
        client_socket.send(message.encode('utf-8'))

# 创建socket对象
server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

# 绑定IP地址和端口号
server_socket.bind(('localhost', 8888))

# 监听连接
server_socket.listen(5)
print("服务器已启动，等待客户端连接...")

while True:
    # 接受客户端连接
    client_socket, addr = server_socket.accept()
    print("客户端已连接：", addr)

    # 创建两个线程，分别用于接收和发送消息
    receive_thread = threading.Thread(target=receive_message, args=(client_socket,))
    send_thread = threading.Thread(target=send_message, args=(client_socket,))

    # 启动线程
    receive_thread.start()
    send_thread.start()
