class NamedList(list):
   def __init__(self, a_name):
      list.__init__([])
      self.name = a_name

if __name__ == ‘__main__‘:
   johnny = NamedList(‘John Paul Jones‘)
   print(johnny)
   print(type(johnny))
   print(dir(johnny))
   johnny.append(‘Bass Player‘)
   johnny.extend([‘Composer‘, ‘Arranger‘, ‘Musician‘])
   print(johnny)
   print(johnny.name)
