Unresolved attribute with argparse

When creating an app using argparse and python 3.4 I get a lot of "Unresolved attribute reference" errors.

Is there any way to fix this?


class Demo:
    def __init__(self):
    self.parser.add_argument('test', type=int, choices=range(0,2), help='pick a number')
    # Add all arguments to the local namespace
    self.parser.parse_args(namespace=self)


if __name__ == '__main__':
    new = Demo()
    # this will generate the error
    print(new.test)
