Solve the following python programming problem given the following code:
def create_reader(note_type, body_reader) : 
    def read_notes_xml_element(element) : 
        note_elements = lists.filter (_is_note_element, element.find_children (('w:' + note_type))) 
        return results.combine (lists.map (_read_note_element, note_elements)) 
def _is_note_element(element) : 
        return (element.attributes.get ('w:type') not in ['continuationSeparator', 'separator']) 
def _read_note_element(element) : 
        return body_reader.read_all (element.children).map ((lambda body : documents.note (note_type = note_type, note_id = element.attributes ['w:id'], body = body))) 
return body_reader
