类的实例化过程

Posted 2020-10-13

例代码：

 1 class Dog(object):
 2 
 3     def __init__(self,name):
 4         self.Name = name
 5 
 6     def shout(self):
 7         print("%s wang...wang...wang!" %self.Name)
 8 
 9 
10 
11 a = Dog(‘gg‘)     #Dog(a,‘gg‘)将a传给self，相当于a.Name = name
12 a_2 = Dog(‘yy‘)
13 
14 a.shout()          #将a.shout(d)穿给shout(self)
15 a_2.shout()
