類型錯誤：worker() 採用 0 個位置參數，但給出了 1 個 - TypeError: worker() takes 0 positional arguments but 1 was given

問題：

I'm trying to implement a subclass and it throws the error:我正在嘗試實現一個子類並拋出錯誤：

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
