One finding regarding YDK cisco_ios_xe_bundle API

[Jacky_hotel_california]

Hello Yan,

Good morning!

Could you please have a look below issue ?  The issue was fixed by lower case of "g" in program. But I check API it seems upper

case of “G”.   So I am a bit confusing.  Can you give me some advice ?

Thanks a lot!

from ydk.models.cisco_ios_xe import Cisco_IOS_XE_native as xe_native

interface = xe_native.Native.Interface()

interface.gigabitethernet.append(gigabitethernet)    use lower case of "g" ,  program is correct but if use upper case of "G" , program is failed.   AttributeError: 'Interface' object has no attribute 'Gigabitethernet'

But from Cisco-ios-xe bundle API GigabitEthernet is upper case of "G" . So I am confused. May I know the reason we need to use

lower case of "g".

Thanks a lot

Cisco-ios-xe_bundle API

class Native.Interface.GigabitEthernet  ----- look like G is upper case.

from ydk.models.cisco_ios_xe import Cisco_IOS_XE_native as xe_native

interface = xe_native.Native.Interface()

gigabitethernet = interface.GigabitEthernet()
gigabitethernet.name = "2"
gigabitethernet.description = "configured by YDK"
interface.gigabitethernet.append(gigabitethernet)  ------------program successful

This is correct! The gigabitethernet is a list in the class Cisco_IOS_XE_native.Native.Interface. Please check API.
