学习Python艰难的方式ex40输入错误

Question

我不知道我的代码是如何从Powershell运行的。它给了我这个错误信息：

    Traceback (most recent call last):
  File "ex40.py", line 12, in <module>
    "So I'll stop right here"])
TypeError: object() takes no parameters

这是我的代码：

class Song(object):
    def _init_(self, lyrics):
        self.lyrics = lyrics

    def 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"])

bulls_on_parade = Song(["They rally around the family",
                        "With pockets full of shells"])

happy_bday.sing_me_a_song()
bulls_on_parade.sing_me_a_song()

我在书中看到了其他完全相同的副本以及我的看法（至少我认为），但他们能够运行。
