Python: how to telnet MSAN Cabinet and change port configuration

python is amazing usable programming langue i saw ever,

 well, this topic about the challenge that i faced in my work @TEData ( biggest ISP in egypt) we have a repeated problem that happened when the TE(Telecom Egypt) specialist assign the new ADSL user to the TEData Vlan ( vlan number look like 405 - 420 ....etc) but he assign customer to another vlan by mistake so our customer can't reach has ADSL service plus customer showing the another ISP (like Nour - Orange - Vodafone) portal 

this case usually escalated to us to re-assign the customer  to the correct Vlan, we have a full queue by the same cases , i written a python script that offer the sample solution it works as :

1- Telnet the huawei MSAN Cabinet 5600T

2- looking for the correct stacking Vlan

3- check if the desired port is configured OR not.

4- if not configured send message "port not configured"close telnet session 

5- if configured check configuration of the port desired 

6- if the configuration is OK send message "Everything is OK& no problem found "

7- else: replace the correct vlan by the port configuration 

8- send message    "the vlan changed from "wong number " to the "correct vlan number"

9-close telnet session 

I'll upload the code soon  you can check the below part of code :

import telnetlib

import sys
import time
import re
