我正在尝试创建一个文本游戏的用户界面

这很好，但是我想创建我自己的简单打印函数来打印到UI的各个部分（在示例中是QLabel）。如果函数在UI文件中，但当我将函数移动到另一个文件时，我得到

“AttributeError:类型对象'Window'没有属性'label'”

即使我的IDE说Window.label在运行之前存在

这是怪癖还是QT？还是我犯了一个错误

我认为问题在于，您试图进行面向对象编程，但实际上并没有进行面向对象编程。例如，您试图在

Game.py

的

Game

类中使用

窗口

类，只需导入它并调用它的函数即可。相反，您需要做的是使用继承。也就是说，您的

Game.py

的

Game

类应该继承自您的

UI.py

窗口的

类
将您的Game.py
更改为以下内容：
from UI import Window

class Game(Window): # Game is inheriting from Window
    def __init__(self):
        Window.__init__(self) # Game is inheriting Window class attributes & functions

    def print_UI(self,*Args, **Kwargs):        
        self.setup.output.insertPlainText(*Args, **Kwargs) # self refers to Game as well as Window class 

    def print_label(self,*Args, **Kwargs):        
        self.label.setText(*Args, **Kwargs) # self refers to Game as well as Window class

    def test():        
        Game.print_label("HI")

您可以查看函数的说明，而不是使用窗口。

您可以将窗口对象作为参数传递给游戏的构造函数，而不是在窗口类中导入游戏，并在游戏中再次导入窗口，因为这样会使标签成员未初始化
