Python implements a simple example of instant messaging based on socket

This article illustrates Python's simple instant messaging based on socket. To share for your reference, specific as follows:

The client tcpclient py

# -*- coding: utf-8 -*-
import socket
import threading
#  The target address IP/URL And the port 
target_host = "127.0.0.1"
target_port = 9999
#  create 1 a socket object 
client = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
#  Connection between a host 
client.connect((target_host,target_port))
def handle_send():
  while True:
    content = raw_input()
    client.send(content)
def handle_receive():
  while True:
    response = client.recv(4096)
    print response
send_handler = threading.Thread(target=handle_send,args=())
send_handler.start()
receive_handler = threading.Thread(target=handle_receive,args=())
receive_handler.start()

Server-side tcpserver.py

# -*- coding: utf-8 -*-
import socket
import threading
#  Listen to the IP And the port 
bind_ip = "127.0.0.1"
bind_port = 9999
#socket  Server initialization 
server = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
server.bind((bind_ip,bind_port))
server.listen(5)
print "[*] Listening on %s:%d" % (bind_ip,bind_port)
#  Define a function handle_client, The input parameters client_socket
def handle_client():
  while True:
    request = client_socket.recv(1024)
    print "[*] Received:%s" % request
def handle_send():
  while True:
    content = raw_input()
    client_socket.send(content);
# Blocking here, waiting to receive data from the client 
client_socket,addr = server.accept()
print "[*] Accept connection from:%s:%d" % (addr[0],addr[1])
# create 1 A thread 
client_handler = threading.Thread(target=handle_client,args=())
client_handler.start()
send_handler = threading.Thread(target=handle_send,args=())
send_handler.start()
