如何解决属性错误? [英] How do I solve an attribute error?

问题描述

因此，就像我在代码(或我正在处理的当前项目)充满错误之前所说的那样.到目前为止，我至少已经解决了十二个或更多的错误，老实说，我只是放弃了.我的意思是上帝知道还有多少.

So like I said before my code (Or my current project that I am working on) is riddled with errors. So far I have at least solved a dozen errors or more and honestly I just give up. I mean God knows how many more there are.

我当前遇到的问题是AttributeError，我认为这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条模式，并且不知道如何解决该问题.

The current problem that I am having is an AttributeError which is in my opinion one of the easiest errors to fix however I seem to have gone in to complete spaghetti mode and I have no clue on how to fix the problem.

{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'

}

我将在下面列出代码，但我觉得我应该解释我要做什么，因此您对代码有某种了解. 基本上在主循环中，我调用类屏幕" ，这有助于创建一个PyGame屏幕，该屏幕一旦运行即可显示.在该屏幕上，我试图使矩形以固定位置显示在屏幕上(坐标是特定的，但我在代码中使用的只是用于测试目的).然后，我有另一个名为"Pane" 的类，并且该类在那里，因此我可以在屏幕内绘制该类窗格的许多实例(如果这样的话).

I will list the code below but I feel as if I should explain what I am trying to do so you have some sort of understanding of the code. Basically in the main loop I call upon the "Class Screen" which helps to create a PyGame screen that comes up once run. On that screen I am trying to get rectangles to appear on the screen in fixed positions (The coordinates are specific but the ones I use on the code are just for test purposes). I then have another class that is called "Pane" and this class is there so that I can draw many instances of the class pane within screen (If that makes sense).

如果有人可以帮助我摆脱错误的帮助，但是如果您认为这不是解决问题的好方法，请成为我的客人提出或教我一个更好的方法做同一件事的方法.

If someone can help me get rid of the error that would be of grate help, but if you think that this is not a good way of solving the problem then please be my guest to come up with or teach me of a better way to do the same thing.

推荐答案

解决您的问题.

class Pane():

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

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