python使用socket向客户端发送数据的方法

import socket, sys
port = 55555
host = 'localhost'
data = "test" * 10485760 # 40MB of data
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((host, port))
byteswritten = 0
while byteswritten < len(data):
  startpos = byteswritten
  endpos = min(byteswritten + 1024, len(data))
  byteswritten += s.send(data[startpos:endpos])
  sys.stdout.write("Wrote %d bytes\r" % byteswritten)
  sys.stdout.flush()
s.shutdown(1)
print "All data sent."
while 1:
  buf = s.recv(1024)
  if not len(buf):
    break
  sys.stdout.write(buf)
