def get_argument(self, name, default=None):
return getattr(self._argparse_arguments, name, default)<EOL>
Get argument value from last :meth:`load_arguments` call.

Keep in mind :meth:`argparse.ArgumentParser.parse_args` generates
its own command-line arguments if `dest` kwarg is not provided,
so ie. `--my-option` became available as `my_option`.

:param name: command-line argument name
:type name: str
:param default: default value if parameter is not found
:returns: command-line argument or default value
