服务端：

import socket, threading
import datetime, os

client_list = []
st = socket.socket(socket.AF_INET, socket.SOCK_STREAM, 0)
st.bind(('192.168.0.118', 8888))
st.listen()


def server_target(server_socket, addr):
    while True:
        cval = server_socket.recv(2048).decode('UTF-8')
        if cval is not None:
            print('客户端:', addr[0], '，内容:', cval)
            for cl in client_list:
                cl.send(('主机回复：%s' % cval).encode('utf-8'))
            with open('txtinfo.txt', 'ab', True) as f:
                f.writelines((str(datetime.datetime.today()).encode('UTF-8'),
                              ('-客户端地址:' + addr[0] + '-发送内容:' + cval).encode('UTF-8'),
                              (('-主机回复：%s' % cval) + os.linesep).encode('UTF-8')))
while True:
    # 代表通讯的socket和客户端地址
    vala, addr = st.accept()
    # 保存对应的sockt到列表中
    client_list.append(vala)
    print(addr)
    with open('txtinfo.txt', 'ab', True) as f:
        f.write((str(datetime.datetime.today()) + '-客户端地址:' + str(addr[0]) + os.linesep).encode('UTF-8'))
        # 为客户端对应的sockt启动对应的线程
    threading.Thread(target=server_target, args=(vala, addr)).start()

客户端：

通过threading.Thread创建线程

import socket, threading

# 简单的客户端
# st = socket.socket(socket.AF_INET, socket.SOCK_STREAM, 0)
# # 调用connect连接服务器
# st.connect(('192.168.0.118', 8888))
# #一旦建立连接成功之后，server于client虚拟链路连接成功
# print(st.recv(2048).decode('UTF-8'))

st = socket.socket(socket.AF_INET, socket.SOCK_STREAM, 0)
st.connect(('192.168.0.118', 8888))


# 读取

        if getser is not None :
            print(getser)
        else:
            break


threading.Thread(target=get_server, args=(st,)).start()
# 发送
while True:
    inp = input()
    # 如果为空或者输入exit 则退出循环
    if inp is None or inp == 'exit':
        break
    # 发送数据
    st.send(inp.encode('UTF-8'))
