类型错误：worker() 采用 0 个位置参数，但给出了 1 个 - TypeError: worker() takes 0 positional arguments but 1 was given

问题：

I'm trying to implement a subclass and it throws the error:我正在尝试实现一个子类并抛出错误：

TypeError: worker() takes 0 positional arguments but 1 was given

class KeyStatisticCollection(DataDownloadUtilities.DataDownloadCollection):
    def GenerateAddressStrings(self):
        pass    
    def worker():
        pass
    def DownloadProc(self):
        pass
