python 新式类的 __getattribute__

class C(object):
    a = ‘abc‘
    def __getattribute__(self, *args, **kwargs):
        print("__getattribute__() is called")
        return object.__getattribute__(self,args[0])
        
    def __getattr__(self, name):
        print (‘hhh‘)
        if name == ‘adult‘:
            return True
            
        else: raise AttributeError(name)
    

a=C()
c=a.a#打印__getattribute__ is called 返回属性的value‘abc‘
b=getattr(a,‘adult‘,7)#先打印__getattribute__ is called,后打印hhh,b为True
print b
