Question

就像我在我的代码（或者我正在处理的当前项目）之前所说的那样充满了错误。到目前为止，我至少已经解决了十几个错误或更多，老实说，我只是放弃了。我的意思是上帝知道还有多少。

我目前遇到的问题是一个AttributeError，在我看来是最容易修复的错误之一，但是我似乎已经完成了意大利面模式而且我不知道如何解决这个问题。

{错误本身：

Traceback (most recent call last):
      File "C:\Users\Burak\Desktop\boxtrial.py", line 87, in <module>
        myScreen.addPane("1")
      File "C:\Users\Burak\Desktop\boxtrial.py", line 67, in addPane
        myPane.drawPane()
      File "C:\Users\Burak\Desktop\boxtrial.py", line 19, in drawPane
        self.Screen.blit(self.font.render(textToDisplay, True, (black)), (250, 115))
AttributeError: 'Pane' object has no attribute 'Screen'

}

我将列出下面的代码，但我觉得我应该解释一下我想要做什么，这样你就可以对代码有一些了解。基本上在主循环中我调用“类屏幕”，这有助于创建一旦运行就出现的PyGame屏幕。在那个屏幕上，我试图让固定位置的屏幕上出现矩形（坐标是特定的，但我在代码中使用的只是出于测试目的）。然后我有另一个名为“Pane”的类，这个类就在那里，这样我就可以在屏幕中绘制类窗格的许多实例（如果这样做有意义）。

如果有人可以帮助我摆脱那些会引起帮助的错误，但是如果你认为这不是一个解决问题的好方法那么请成为我的客人提出或教我一个更好的做同样事情的方法。

修复你的案子。

class Pane():

    def __init__(self, textToDisplay, coordinates, screen):
         ...
        self.screen = screen

    def drawPane(self):
        self.Screen.... # <<< HERE
