服务器端：

import socket

server = socket.socket()

server.bind(("10.7.156.69",17892))

server.listen(512)
#保持服务器一直运行
while True:
    client,user = server.accept()
    s = "================\n1、发送图片\n2、发送文字\n3、通知结束\n==================="
    client.send(s.encode("utf-8"))
    #保持通信
    while True:
        message_re = client.recv(1024).decode("utf-8")
        if message_re == "1":
            with open("./147014999.jpg","rb") as f:
                image = f.read()
                client.send(image)
            client.close() #断开会话
        elif message_re == "2":
            client.send("你怎么这么帅！".encode("utf-8"))
            client.close()
        elif message_re == "3":
            client.send("感谢使用，再见".encode("utf-8"))
            client.close()
            break
    client.close()
    break

客服端

import  socket

#1、创建套接字对象默认  使用IPv4和TCP协议
client = socket.socket()
#2、连接到服务器(需要指定IP地址和端口)
client.connect(("10.7.156.69",17892))
print(client.recv(1024).decode("utf-8"))

while True:
        message = input("请输入选择：")
        #想服务器发送数据
        client.send(message.encode("utf-8"))
        data = bytes()
        image = client.recv(1024)
        if message == "1":
            f = open("./aa.jpg", "wb")
            while image:
                data += image
                image = client.recv(1024)
                print("正在接收................")
            f.write(data)
            f.close()
            print("接收完成")
        elif message == "2":
            with open("./aa.txt","w",encoding="utf-8") as f:
                f.write(image.decode("utf-8"))
                f.close()
        elif message == "3":
            print(client.recv(1024).decode("utf-8"))
            break
        # 3、从服务器接收数据
        #print(client.recv(1024).decode("utf-8"))
        #4、断开连接
