python "TypeError: object() takes no parameters"

class Song(object):def __init__(self, lyrics):self.lyrics = lyricsdef sing_me_a_song(self):for line in self.lyrics:print (line)happy_bday = Song(["Happy birthday to you",   "I don't want to get sued",   "So I'll stop right here"])happy_bday.sing_me_a_song() 

init()的下划线竟然是两个！！！
