windows系统，socket编程实现两台计算机之间通信

Question

socket编程实现两台计算机之间通信，windows系统下用python编程

import socket

BUFSIZE = 1024
ip_port = ('127.0.0.1', 9000)

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM )
s.bind(ip_port)
s.listen(5)

client, client_addr = s.accept()
print(client, client_addr)

msg = s.recv(BUFSIZE)

print(msg, type(msg))

client.send(msg.upper())

client.close()
s.close()

CLIENT
#!/usr/bin/env python
#coding:utf-8
#Created by Andy @ 2017/9/14

import socket

BUFSIZE = 1024
ip_port = ('127.0.0.1', 9000)

client = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

client.connect(ip_port)
client.send('Andy is here'.encode('utf-8'))
feedback = client.recv(BUFSIZE)
print(feedback.decode('utf-8'))
client.close()

两台计算机连接同一个热点，而且ip地址也已经改变，但是无法通信，求帮助！

如果是连127.0.0.1 应该不会出现这个提示，把防火墙暂时关闭试试。
