XE examples.

Seeing a lot of python based XR samples in github but not on XE.  The XR hello world also uses a systemTime call that doesn't exist in XE... Are these examples posted anywhere.

Watch the blog on VLANs. : http://www.marcuscom.com/pgp.asc 

 We don't yet have as many published samples for XE as we have for XR, but here is a simple one to get you going. Shows how to query for interfaces and set the description, using the IOS-XE "native" model.

 from ydk.types import Empty

from ydk.errors import YPYError

from ydk.services import CRUDService

from ydk.providers import NetconfServiceProvider 

from ydk.models.cisco_ios_xe import Cisco_IOS_XE_native as n

from ydk.models.cisco_ios_xe import Cisco_IOS_XE_environment_oper as e 

def query_and_print_gi(service, session):

    '''query for gigabit ethernet interfaces, print name & description'''

    q_intf = n.Native.Interface()

    intf = service.read(session, q_intf)

    for i in intf.gigabitethernet:

        print(i.name, i.description) 

def query_for_gi_names(service, session):

    '''query for gigabit ethernet interface names'''

    q_intf = n.Native.Interface()

    intf = service.read(session, q_intf)

    return  

def set_gi_descr(service, session, intf_name, new_descr):

    w_intf = n.Native.Interface.Gigabitethernet()

    w_intf.name = intf_name

    w_intf.description = new_descr

    intf = n.Native.Interface()

    intf.gigabitethernet.append(w_intf)

    r = service.create(session, intf) 

1. create the provider

session = NetconfServiceProvider(

    address='127.0.0.1',

    port=2223,

    username='vagrant',

    password='vagrant',

    protocol='ssh') 

1. Initialize a CRUD service

c = CRUDService() 

names = query_for_gi_names(c, session)

if len(names)>0:

    set_gi_descr(c, session, names[0], 'first gi interface')

if len(names)>1:

    set_gi_descr(c, session, names[-1], 'last gi interface')

query_and_print_gi(c, session)

 Changed a few things so that it would work in Python3. Also added some stuff to make sure that it could be understood how it all worked.
