1、class Flower: def __init__(self, name): self.name = name print("This is %s" %self.name) dandelion = Flower("dandelion")#首先我们定义一个类，这是一个花类，属性是打印花的品名。
2、class Flower: def __init__(self, name): self.name = name print("This is %s" %self.name) def __del__(): #这里要运用__del，定义的方法类似函数。
3、class Flower: def __init__(self, name): self.name = name print("This is %s" %self.name) def __del__(self): #但是务必记得要加上self。
4、clas衡痕贤伎s Flower: def __init__(self, name): self.name = name print("This is %s" %self.name) def __del__(self): print("The end!") dandelion = Flower("dandelion") #设置后再运行一下就会发现最后多了一行，其实就是程序运行的最后会显示__del__的设置。
5、class Flower: def __init__(self, name): self.name = name print("This is %s" %self.name) def __del__(self): print("The end of %s" %self.name) dandelion = Flower("dandelion")#同样的，__del__也是可以调用属性的。
6、clas衡痕贤伎s Flower: def __init__(self, name): self.name = name print("This is %s" %self.name) def __del__(self): print("The end of %s" %self.name)del dandeliondandelion = Flower("dandelion")#从这个语句就可以看出执行的顺序了。
