The indentation certainly makes your code very hard to read. I suspect the reason that you are seeing multiple lists is that your print call is within the for loop. Here's how to fix that:

def snmpWALK(request):
    all_lists = []
    if request.method=='GET':
        host= 'localhost'
        oid = '1.3.6.1.2.1.1.9.1.2'        
        for t in nextCmd(
                SnmpEngine(),
                CommunityData('public'),
                UdpTransportTarget((host, 161)),
                ContextData(),
                ObjectType(ObjectIdentity(oid)),
                lookupMib=False,
                lexicographicMode=False):
            # I broke this up for purposes of formatting 
            # on SO.  normally, I would just stick these in
            # the for loop above.
            errorIndication, errorStatus = t[0], t[1]
            errorIndex, varBinds = t[2], t[3]
            if errorIndication:
                print(errorIndication, file=sys.stderr)
                break
            elif errorStatus:
                print('%s at %s' % (
                    errorStatus.prettyPrint(),
                    errorIndex and varBinds[int(errorIndex) - 1][0] or '?'
                ), file=sys.stderr)
                break
            else:
                MyList = []
                for varBind in varBinds:
                    thing='%s = %s' % varBind
                    MyList.append(thing)
            # this is within the for loop!!!
            print(MyList)
            

In general, your code was fairly hard to read for those of us that like to help out on SO because (1) it was improperly indented (you can see the break statements in the OP) and (2) it didn't follow PEP8. YMMV if you want to follow these conventions / suggestions, it's just a lot easier to help you if you do.
