這篇文章主要為大家詳細介紹了python實現(xiàn)點對點聊天程序，具有一定的參考價值，感興趣的小伙伴們可以參考一下

用Python實現(xiàn)點對點的聊天，2個程序，一個是client.py，一個是server.py，通過本機地址127.0.0.1連接進行通信，利用多線程把發(fā)送消息和接收消息分開獨立進行。

client代碼：

import socket
import sys
import threading
import time
 
class client():
 def __init__(self):
  self.s = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
  self.ip = "127.0.0.1"
 
 def connect(self):
  try:
   self.s.connect((self.ip,8888))
   print("connect success")
   print('connect time: '+time.ctime())
  except ConnectionError:
   print('connect error')
   sys.exit(-1)
  except:
   print('unexpect error')
   sys.exit(-1)
 
 def send_sth(self):
  while True:
   sth=input('say something:\n')
   try:
    self.s.sendall(sth.encode('utf-8'))
   except ConnectionError:
    print('connect error')
    sys.exit(-1)
   except:
    print('unexpect error')
    sys.exit(-1)
 
 def receive(self):
  while True:
   try:
    r=self.s.recv(1024)
    print ('get message:'+r.decode('utf-8'))
   except ConnectionError:
    print('connect error')
    sys.exit(-1)
   except:
    print('unexpect error')
    sys.exit(-1)
 
c1 = client()
c1.connect()
threading._start_new_thread(c1.receive,())
c1.send_sth()

server代碼：

import socket
import sys
import threading
import time
 
def server():
 def bind():
  HOST='127.0.0.1'
  s.bind((HOST,8888))
  print("bind ok")
 
 def listen():
  s.listen(10)
  print ('Socket now listening')
 
 def send_sth(conn):
  while True:
   try:
    sth=input('say something:\n')
    conn.sendall(sth.encode('utf-8'))
   except ConnectionError:
    print('connect error')
    sys.exit(-1)
   except:
    print('unexpect error')
    sys.exit(-1)
 
 def recv(conn):
   while True:
   try:
    data=conn.recv(1024)
    data2=data.decode('utf-8')
    print('get message:'+data2)
   except ConnectionError:
    print('connect error')
    sys.exit(-1)
   except:
    print('unexpect error')
    sys.exit(-1)
 
 s=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
 bind()
 listen()
 conn,addr=s.accept()
 print("connect success")
 print('connect time: '+time.ctime())
 threading._start_new_thread(recv,(conn,))
 send_sth(conn)
 
if __name__=='__main__':
 server()

開啟多線程有2種方法，上面2個程序都是用函數(shù)的方法，還有一種方法是用類繼承threading類

代碼：

import socket
import threading
class client(threading.Thread):
 def __init__(self,sth):
  threading.Thread.__init__(self)
  self.sth=sth
 def run(self):
  s=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
  ip="127.0.0.1"
  try:
   s.connect((ip,8888))
  except :
   print('con error')
   exit()
  #print("connect success")
  s.sendall(self.sth.encode('utf-8'))
  #print("send success")
  try:
   r=s.recv(1024)
  except:
   print('recv error')
   exit()
  print (r.decode('utf-8'))
c1=client('hello 1')
c1.start()
c2=client('hello 2')
c2.start()
