Paramiko output printing issue

[anna]

Here is my first ssh script, facing stdout printing issue

import socket
socket.setdefaulttimeout(5)
import paramiko
import sys
import threading
import os
import time
ip        = '10.124.117.12'
user      = 'ops'
passwd    = 'BN123'

ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
try:
   ssh.connect(ip,username=user,password=passwd, timeout=5)
   print "Connected to %s" % ip
   time.sleep(5)
   connection = ssh.invoke_shell()
   stdin, stdout, stderr = ssh.exec_command("show chassis\n")
   result = stdout.read().decode('ascii').strip("\n")
   ssh.close()
   print result
except paramiko.AuthenticationException:
       print "[-] Authentication Exception! ..."
except paramiko.SSHException:
       print "[-] SSH Exception! ..."
