Is there any way to tell if an arg value was defaulted vs. set on command line?
No. If you need to determine that, don't set a default value in the
add_argument() method. Then just check for None and replace it with the default
value and do whatever other processing for the case where the user does not
specify that argument.
parser.add_argument('-f', '--foo', help="the foo argument [default: bar]")
args = parser.parse_args()
if args.foo is None:
args.foo = 'bar'
print 'I'm warning you that you did not specify a --foo argument.'
print 'Using default=bar.'
