python基于socket实现的UDP及TCP通讯功能示例

import socket
address = ('127.0.0.1', 31500)
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
s.bind(address)
while True:
  data, addr = s.recvfrom(2048)
  if not data:
    print "client has exist"
    break
  print "received:", data, "from", addr
s.close()

import socket
address = ('127.0.0.1', 31500)
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
while True:
  msg = raw_input()
  if not msg:
    break
  s.sendto(msg, address)
s.close()
