Python Simple Remote Control Single Threaded Version

In this article, the example for you to share the python simple remote control of the specific code for your reference, the specific content is as follows

1. Technology: pipeline communications, streaming file handling, socket basics

2. Tips：

Default IP: 127.0.0.1

Default port: 7676

3. Code samples:

Server:

#!/usr/bin/env python  
# encoding: utf-8  
 
import socket 
import sys 
from os import * 
 
reload(sys)  
("utf-8")

  s = (socket.AF_INET,socket.SOCK_STREAM) 
  return s 
 
def socketDeal(s,HOST,PORT): 
  ((HOST,PORT)) 
  (1) 
 
def ControlModule(sS,addr): 
  recv_buffer = (20048) 
  if recv_buffer == "[-]Error:Server is OFF" or recv_buffer == "[*]Server is OFF": 
    print recv_buffer 
    (0) 
  else: 
    print recv_buffer 
  send_buf = raw_input(addr[0]+">") 
  (send_buf) 
 
 
def main(): 
  HOST = "127.0.0.1" 
  PORT = 7676 
  s = socketInit() 
  socketDeal(s, HOST, PORT) 
  sS,addr = () 
  print "Connect from " + addr[0] + ":" + repr(addr[1]) 
  try: 
    while True:
