  class ScreenOne(Screen):
  
      def __init__(self,**kwargs):
          super(ScreenOne,self).__init__(**kwargs)
          self.box = BoxLayout(orientation='vertical')
  
          self.label1 = Label(text="One label on screen 1")
          self.label2 = Label(text="Another label label")
  
          self.button = Button(text="Go to screen 2")
          self.button.bind(on_press=self.change_screen)
  
          self.box.add_widget(self.label1)
          self.box.add_widget(self.label2)
  
          self.box.add_widget(self.button)
  
          self.add_widget(self.box)
  
      def change_screen(self,*args):
          self.manager.current = 'screen2'
  
  
  
  class ScreenTwo(Screen):
      def __init__(self,**kwargs):
          super (ScreenTwo,self).__init__(**kwargs)
  
          self.box = BoxLayout(orientation='vertical')
  
          self.label1 = Label(text="One label on screen 2")
          self.label2 = Label(text="Another label label")
  
          self.button = Button(text="Go to screen 1")
          self.button.bind(on_press=self.change_screen)
  
          self.box.add_widget(self.label1)
          self.box.add_widget(self.label2)
  
          self.box.add_widget(self.button)
  
          self.add_widget(self.box)
  
      def change_screen(self,*args):
          self.manager.current = 'screen1'
  
  
  
  class MyApp(App):
      def __init__(self,**kwargs):
          super(MyApp,self).__init__(**kwargs)
          self.sm = ScreenManager()
  
          self.sm.add_widget(ScreenOne(name = "screen1"))
          self.sm.add_widget(ScreenTwo(name = "screen2"))
  
  
      def build(self):
          return self.sm
  
  
  
  if __name__ == "__main__":
      MyApp().run()
