What's happening is probably: the server is sending the data
in chunks, and you're calling recv() before all of the output
has been received.

You might want to try:

  # receive the data and print it
  sockfile = sockobj.makefile('r')
  data = sockfile.readline()
  print data

The "readline()" method waits for the whole line of data
to arrive.  If that's not good enough, you can write a simple
loop yourself, to gather data until you have all the data you
want.
