Solve the following python programming problem given the following code:
def RaiseNotImplementedMethod(property_class, explanation = None) : 
    'Wrapper method that returns a method which always fails.

  Args:
    property_class: A property class
    explanation: An optional argument explaining why the given property
        has not been implemented

  Returns:
    A method which will always raise NotImplementedError. If explanation is
        included, it will be raised as part of the exception, otherwise, a
        simple explanation will be provided that uses the name of the property
        class.
  ' 
    if (explanation is None) : 
        explanation = ("The property %s can't be used to define an EndpointsModel." % (property_class.__name__,)) 
def RaiseNotImplemented(unused_prop, unused_index) : 
        'Dummy method that will always raise NotImplementedError.

    Raises:
      NotImplementedError: always
    ' 
        raise NotImplementedError (explanation) 
return property_class
