Python socket client doesn't exit

I'm trying to develop my simple server/client scripts to send some useful information about systems using platform module and saved in .txt file on the server side ( in order o improve my programming skills ) but when I run the client side it doesn't send any information till I closed using Ctrl+c but what I really want is the client to send informations then it close itself I tried the sys.exit but it doesn't work

this is the server Side 

#!/usr/bin/python
import socket
import  sys
host = ' '
port = 1060
s = socket.socket()
s.bind(('',port)) #bind server
s.listen(2)
conn, addr = s.accept()
print addr , "Now Connected" 
response =  conn.recv(1024)
print response
saved = open('saved_data.txt','w+')
saved.write(response) # store the received information in txt file

conn.close()

and this is the client side 

#!/usr/bin/python
import socket
import platform
import  sys


def socket_co():
   port = 1060
   s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
   s.connect(('192.168.1.107', port)) # my computer address and the port
   system = platform.system()
   node = platform.node()
   version = platform.version()
   machine = platform.machine()
   f = s.makefile("r+") #making file to store information ( as I think it do ) using the makefile()
   f.write('system: ' + str(system) + '\n')
   f.write('node: ' + str(node) + '\n')
   f.write('version: ' + str(version) + '\n')
   f.write('machine: ' + str(machine) + '\n')
   sete = f.readlines() #read lines from the file
   s.send(str(sete))
   while True:
       print "Sending..."
   s.close()
   sys.exit() #end the operation


   def main():
       socket_co()

   if __name__ == '__main__':
       main()

Data is cached in memory before sending. You have to flush after writing:

   f = s.makefile("r+") #making file to store information ( as I think it do ) using the makefile()
   f.write('system: %s\n' % system)
   f.write('node: %s\n' % node)
   f.write('version: %s\n' % version)
   f.write('machine: %s\n' % machine)
   f.flush()

while True:
       print "Sending..."

loops forever. So the problem is not in the send part.
