python实现单聊群聊的聊天室

以下是Python实现单聊和群聊的聊天室的示例代码：

1. 单聊

import socket

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

# 获取本地主机名
host = socket.gethostname()

# 设置端口号
port = 9999

# 绑定端口号
server_socket.bind((host, port))

# 设置最大连接数，超过后排队
server_socket.listen(5)

while True:
    # 建立客户端连接
    client_socket, addr = server_socket.accept()

    print("连接地址: %s" % str(addr))

    msg = '欢迎访问菜鸟教程！' + "\r\n"
    client_socket.send(msg.encode('utf-8'))

    client_socket.close()

2. 群聊

import socket
import threading

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

# 获取本地主机名
host = socket.gethostname()

# 设置端口号
port = 9999

# 绑定端口号
server_socket.bind((host, port))

# 设置最大连接数，超过后排队
server_socket.listen(5)

# 客户端列表
client_list = []


# 处理客户端消息
def handle_client(client_socket, addr):
    while True:
        try:
            msg = client_socket.recv(1024).decode('utf-8')
            if msg:
                print("收到来自%s的消息：%s" % (str(addr), msg))
                broadcast(msg, client_socket)
            else:
                remove(client_socket)
        except:
            continue


# 广播消息
def broadcast(msg, client_socket):
    for client in client_list:
        if client != client_socket:
            try:
                client.send(msg.encode('utf-8'))
            except:
                client.close()
                remove(client)


# 移除客户端
def remove(client_socket):
    if client_socket in client_list:
        client_list.remove(client_socket)


while True:
    # 建立客户端连接
    client_socket, addr = server_socket.accept()

    client_list.append(client_socket)

    print("连接地址: %s" % str(addr))

    # 创建新线程来处理客户端消息
    client_thread = threading.Thread(target=handle_client, args=(client_socket, addr))
    client_thread.start()
