也许有人为能帮助我。

EDIT1： 当我做，所以

def spielen(self, event,): 
     print("spielen") 
     self.label1 = QtWidgets.QLabel(self) 
     self.label1.hide() 

比我得到的控制台消息spielen但标签仍然存在 当我愿意这样做：

def spielen(self, event,): 
    print("spielen") 
    self.label1.hide() 

比程序崩溃

如果你想引用你已经在类中创建对象时，你需要将其声明为这个类的一个属性，与self.labelX：

self.label1 = QtWidgets.QLabel(self) 

然后在这个类中的任何方法，你可以方便地调用这个属性：

self.label1.hide() 

或其他地方的日E码

window_inhalt_instance.label1.hide()

编辑： 我专注于你如何实例化类，你需要在这里改变一些地方过于：

标签不隐藏，因为它们被创建与WindowInhalt.label(self)

当你的类窗口从WindowInhalt继承，你可以直接叫

self.label() # in initme(), same for the buttons 

但你需要更改WindowInhalt每个标签声明，通过添加自
