#根据作为参数引入的主题打开链接的函数

def SCHOOL(Subject):
                    webbrowser.open_new_tab(School[Subject])
        
            def build(self):
                self.theme_cls.primary_palette = "Indigo"
                self.root = Builder.load_string(root_kv)
        
        if __name__ == "__main__":
            MainApp().run()

   

我希望制作一个可以从字典中获取链接并根据函数调用打开它的函数。但我是第一次尝试使用 Kivy MD，我需要帮助
