something going wrong.. code is not working

[buran]

as I said line will have new lien - '\n' at the end and you need to strip it.

#!/usr/bin/python

# load easysnmp module
from easysnmp import Session
#Community for the device
community ='public'
#sysDescr OID
oid ='SNMPv2-MIB::sysDescr.0'
with open('DSLAMIP.txt') as ipfile:
    for sr_no, line in enumerate(ipfile, start=1):
        ip = line.strip()
        try:
            session = Session(hostname=ip, community=community, version=2)
            snmp_get = session.get(oid)
            result = snmp_get.value.encode('ascii')
            if 'IES1248-51' in result:
                model = 'ZyXEL'
            elif 'ECI' in result:
                model = 'ECI'
            elif 'IP' in result:
                model = 'UT'
            print('{} {} {}'.format(sr_no, ip, model))
        except Exception as excp:
            print('Something went wrong!')
            print(excp)
