What is the best style for a Python method that requires the keyword argument 'required_arg':

def test_method(required_arg, *args, **kwargs:


def test_method(*args, **kwargs):
    required_arg = kwargs.pop('required_arg')
    if kwargs:
        raise ValueError('Unexpected keyword arguments: %s' % kwargs)

Or something else? I want to use this for all my methods in the future so I'm kind of looking for the best practices way to deal with required keyword arguments in Python methods.
