dns drivers - update_record

I know its an edge case but say when we do update_record() and change the 'type' for the record
and if it 'is' RecordType.A then the value for it is 0 and in all the dns drivers I see things like 'if type:' which will never be True isn't it ?

and just fft isn't it a good practice not using keywords like 'type' . Guess we could've used something like record_type or zone_type ? or simply like pep says use 'single_trailing_underscore_:' http://www.python.org/dev/peps/pep-0008/

I guess we need to set those record type constants starting from 1 in RecordType class.
