AttributeError: 'super' object has no attribute 'word_weighting'

Question

我有一个超级class FTM:

class FTM:
    def __init__(self,word_weighting = 'normal'):
        self.word_weighting = word_weighting
    
    def get_sparse_global_term_weights(self, word_weighting):
        pass

和继承自 FTM 的子class：

class FLSA(FTM):
    def __init__(self, word_weighting='normal'):
        super().__init__(word_weighting = word_weighting)
        self.sparse_global_term_weighting = super().get_sparse_global_term_weights(word_weighting = super().word_weighting)

运行这段代码，我得到以下错误：

AttributeError: 'super' object has no attribute 'word_weighting'

我已经初始化了属性。为什么会出现此错误？

Answer 1

super() 只有 return 一系列 绑定方法 来自parent class!

看看这个link：https://realpython.com/python-super/#a-super-deep-dive

By including an instantiated object, super() returns a bound method: a method that is bound to the object, which gives the method the object’s context such as any instance attributes. If this parameter is not included, the method returned is just a function, unassociated with an object’s context.

super()不能return一个class的属性，需要定义一个属性为“word_weighting".

@property
def word_weighting(self):
    return self._word_weighting # attrib: 'word_weighting' was changed it to '_word_weighting'
