【问题描述】：

我做了一个非常简单的程序，大约有 2 个按钮，当按下它们时，它们会在 IDE 终端中显示按下了什么按钮以及按下了多少次。现在我尝试在每个按钮上方的标签中显示计数，我尝试了很多我在互联网上看到的东西，但没有成功，我被困在这里几天......Heeelppp pleasee ！

我试图用 StringProperty() 解决我的问题，但我不知道我做错了什么..

        super().__init__(**kwargs)
        self.numaratoarebtn1 = 0
        self.numaratoarebtn2 = 0
        self.total_label = " initial"

    def update_numaratoarebtn1(self):

        self.numaratoarebtn1 += 1
        self.total = "Total Clicks for Button 1: " + str(self.numaratoarebtn1)
        print(self.total)

    def update_numaratoarebtn2(self):

        self.numaratoarebtn2 += 1
        self.total = "Total Clicks for Button 2: " + str(self.numaratoarebtn2)

        self.parent.ids.counter.update_label(label)

    def update_label(self, param):
        self.param = param
        self.total_label = param
        print(param)



btn = ButoaneleMele()
