Kivy Python - 影响不同函数中的按钮

Question

我试图改变不同方法中按钮的属性。这是我目前正在使用：

def _finish_init(self, dt): 
    self.ids.grid_1.cols = 5 

    def callfun(self, *args): 
     self.ChangePic() 

    # Creating a variable to use to determine if the buttons should be editable 
    binded = 0 

    # Loop to make 15 different buttons on screen 
    for x in range(15): 
     self.buttons.append(Button()) 
     self.ids.grid_1.add_widget(self.buttons[x]) 
     self.buttons[x].background_normal = 'YOUTUBE.png' 
     self.buttons[x].background_down = 'opacity.png' 
     self.buttons[x].bind(on_release=partial(self.HoldButtonNum, x)) 


     # Make the button switch screens to input from calling the function above 
     if edit_mode is True: 
      self.buttons[x].bind(on_release=partial(self.SwitchScreenInput, x)) 

def ChangePic(self, *args): 
     _finish_init().buttons[1].background_normal = 'folder.png' 

当ChangePic叫我的错误：

NameError: name '_finish_init' is not defined

有什么建议？

它看起来像两者的功能是一类的成员，则需要使用

self._finish_init()...
