Python 2.7 像普通OOP类一样，在wx Python中创建类的实例

我试图同时学习OOP和wx Python，我发现在使用wx时创建类实例很困难。我不知道我遗漏了什么，但是看到下面的代码，你可以看到我与循环前最后一行的混淆。在正常的继承场景中，我可以创建DailyStasks类的实例，然后使用该实例调用方法。为什么不在wx？是因为我没有在父类中使用对象类，而是必须使用wx.Frame和wx.Panel吗？我希望我的要求有道理。代码的第一部分是我在没有wx的情况下所期望的行为，第二组代码是让我困惑的wx代码。提前感谢你的帮助

    def eat(self, food):
        print '%s eats the %s'% (self.name, food)

    def breath(self):
        print '%s breaths through lungs'%(self.name)

class Dog(Animals):
    def gets_mad(self):
        print 'When %s gets mad, %s bites'%(self.name, self.name)

    def show_affection(self):
        print '%s shows affection and wags his tail'% (self.name)

    def fetch(self,thing):
        print '%s chases and brings back the %s'% (self.name, thing)

class Cat(Animals):
    def gets_mad(self):
        print 'When %s gets mad, %s will scratch you'%(self.name, self.name)

    def show_affection(self):
        print '%s shows affection and purrs'% (self.name)

    def fetch(self):
        print "%s doesn't fetch anything" % (self.name)

wx应该允许以正常方式继承。当您将dt分配给DailyTask（）实例时，您能否详细说明实际行为是什么？这就是问题所在。当我尝试用dt实例化时，它说它需要2个参数，可能是因为DailyStasks init中的父输入。我试图放在括号中的内容要么没有定义，要么需要wx.window要求。我已尝试删除父项，但这也会导致GUI出现问题。请稍候，您是否尝试发送窗口或窗口子项作为父项。Self是第一个隐含参数，但您需要填充第二个。。。
