两台windows电脑之间通信

一台做客户端，一台做服务端。
服务端：

import os
import socket
import time
from test_pip import pip_test


def server_socket():
    while True:
        ip = ''
        port = 12345    # 端口号可以自取
        s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        s.bind((ip, port))
        s.listen(1)
        print('listen at port:', port)
        conn, addr = s.accept()
        print('connected by ', addr)

        while True:
            from_client_msg = conn.recv(1024)
            if from_client_msg == 'exit':
                break
            else:
                data = from_client_msg.decode('gbk')
                print('接收数据：', data)
                # a = os.system(data)
                # print(a)
                now_time = time.strftime('%Y-%m-%d %H:%M:%S', time.localtime(time.time()))
                send_data = conn.send(
                        (str(now_time) + "服务端已收到:" + from_client_msg.decode('gbk') + ',返回内容：other').encode('gbk'))
        conn.close()
        s.close()


if __name__ == '__main__':
"""永远开启服务"""
    while True:
        try:
            server_socket()
        except Exception as e:
            continue

客户端：

import socket
import sys

def socket_client_fun():

    IP = '127.0.0.1'  # 填写服务器端的IP地址
    port = 12345  # 端口号必须与服务器端一致
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    try:
        s.connect((IP, port))
    except Exception as e:
        print('server not find or not open')
        sys.exit()
    while True:
        trigger = input("请输入发送给服务器的内容:")
        s.sendall(trigger.encode('gbk'))
        data = s.recv(1024)
        data = data.decode('gbk')
        print('recieved:', data)
        if trigger == 'exit':  # 发送exit结束连接
            break
    s.close()


if __name__ == '__main__':
    socket_client_fun()
