我正在尝试实现一个子类,它会抛出错误:

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

帮助我我在这里做错了什么，因为我收到以下错误，

类型错误：fizz_buzz() 采用 0 个位置参数，但给出了 1 个

class FizzBuzz:
    def __init__(self, number_value):
        self.number_value = number_value

    def fizz_buzz():
        if number_value % 3 == 0 and number_value % 5 == 0:
            print("FizzBuzz")
        elif number_value % 3 == 0:
            print("Fizz")
        elif number_value % 5 == 0:
            print("Buzz")
        else:
            return f"{number_value} can't be multiplied by either 3 or 5"

number_value = int(input("Enter number: "))
fizzbuzz_object = FizzBuzz(number_value)
fizzbuzz_object.fizz_buzz()
