为什么我的类不是从父类继承的？

Question

我创建一个子类，但我有使它从父类继承的困难：

def ParentClass(object): 

    def __init__(self,num): 
     self.num = num 
     self.get_soup() 

    def get_soup(self): 
     self.soup = 'soup' 
     return self.soup 

def SubClass(Advert): 

    def __init__(self,num): 
     ParentClass.__init__(self,num) 

    def test(self): 
     print 'it works' 
     print self.num 

if __name__== "__main__": 

    num = 1118868465  
    ad = SubClass(num) 
    ad.test() 

我应该看看在元类？

你具备的功能在你的代码不是类，父类也被称为ParentClass没有广告：

class ParentClass(object): # class not def 
    def __init__(self,num): 
     self.num = num 
     self.get_soup() 

    def get_soup(self): 
     self.soup = 'soup' 
     return self.soup 

class SubClass(ParentClass): # inherit from ParentClass 
    def __init__(self, num): 
     super(SubClass, self).__init__(num) 
    def test(self): 
     print 'it works' 
     print self.num
