python学习笔记（15）object，类，组的学习 今天碰到难题了
1、今天碰到好几个难点，面对对象编程的概念，操作，理解，这几天要好好专研下。
2、object传递参数这个理解了好久
class Song(object):#object用来传递参数的
def __init__(self, lyrics):
#__init__下划线是两横，
#__init__的名字不能改动，
#这是一个固定函数，用来初始化参数值的
#self表示对象自己，lyrics才是对象的值
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 there"])
bulls_on_parade = Song(["They rally around the family",
"With pockets full of shells"])
print(happy_bday)
print(bulls_on_parade)
happy_bday.sing_me_a_song()
bulls_on_parade.sing_me_a_song()
