python socket编程代码实例

client端学会数据的发送哦

# -*- coding: utf-8 -*-

import socket  
import re
import time
s = socket.socket()
host = "xx.xxx.xxx.xxx" # 获取本地主机名
port = xxxx
s.connect((host, port))
while 1:
 data = s.recv(1024)
 print data
 l = []
 for k in range(len(data)):
  if data[k]=='+':
l.append('+')
  elif data[k]=='-':
l.append('-')
 q=re.findall(r'\d+',data)
 if len(q)==10:
  sum = int(q[0])
  for i in range(1,10):
print sum
if l[i-1]=='+':
 sum= sum + int(q[i])
elif l[i-1]=='-':
 sum  =  sum-int(q[i])
  print 'sum='+str(sum)
  emm = str(sum)
  s.send(emm+'\r\n')
  # 果然好多坑
  print s.recv(1024)
s.close()
