PythonTk跨对象编程继承属性

Question

所以我的计划是一个测验，其中有一个主要的类，是一个整体的反应途径与其他类的子反应途径。我如何继承像QUESTIONSTARTER一样在一个页面中定义的按钮和标签，并且可以在另一个类STAGE 2上显示。这对我来说是个大问题，希望你能帮助我。这是两个类的例子：（我不能在question starter中再添加一个方法）所以我希望question starter中的按钮和标签被继承到stage 2中，在stage 2中我可以将按钮网格化到stage 2中

class SETOFQUESTIONS(QUESTIONSTARTER):

def __init__ (self):
    self.NumberOfStages = NumberOfStages
    self.StartingReactant = StartingReactant

def SetStages(self, NumberOfStages):
    #If the quiz type is default and customised set number of stages to a minimum of 3 stages and a max of 5 stages for aliphatic reaction
    #for aromatic -set min stages 2 and max stages 5

    if "Default" == True:
        self.NumberOfStages = 5
        print ("Number Of Stages = ",NumberOfStages)
        return NumberOfStages

    else:
        self.NumberOfStages = CustomisedNumberOfStages

        print ("Number Of Stages = ",CustomisedNumberOfStages)
