Need to get mac address tables from d-link switches with python

Probably I should use SNMP v2c and pysnmp, but can't figure out how can I do that clearly, probably I need a list of port to mac array dictionaries. Anyways I am going to push that into mongodb and then get the port number having the mac address.

Here is the shell command that gives that information

snmpwalk -O0sUX -v2c -Cc -c public 10.77.10.8 BRIDGE-MIB::dot1dTpFdbPort

I'd suggest starting from a script like this. It's not debugged, so if you get it fixed to a fully working condition - please comment and I'd update the code to benefit others.

from pysnmp.hlapi import *

for (errorIndication,
     errorStatus,
     errorIndex,
     varBindTable) in bulkCmd(SnmpEngine(),
                              CommunityData('public'),
                              UdpTransportTarget(('demo.pysnmp.com', 161)),
                              ContextData(),
                              0, 25,
                              ObjectType(ObjectIdentity('BRIDGE-MIB', 'dot1dTpFdbPort')),
                              lexicographicMode=False):
    if errorIndication:
        Exception(errorIndication)
    elif errorStatus:
        Exception(errorStatus)
    else:
        for varBinds in varBindTable:
            for varBind in varBinds:
                # imaginary MongoDB document mapping port-ID -> MAC
                db.portsAndMacs.insert_one(
                    {varBind[1].prettyPrint(): varBind[0].prettyPrint()[-17:]}
                )
