我有一个项目，在一个框架中有多个“小部件”。我将小部件列表传递给一个名为 GUI 的类，该类显示所有这些“小部件”。我的框架上有一个按钮，需要从列表中删除其中一个小部件。它是做什么的。但是小部件本身并没有从框架中消失。
所以澄清一下
GUI 类有一个对象列表[Object, Object, Object, Object]。所以它现在显示 4 个 Widget 对象。当我按下删除按钮时，新列表看起来像 [Object, Object, Object] 但 GUI 类中的列表仍然是 [Object, Object, Object, Object] .我怎样才能使 GUI 始终使用最新版本的列表？
澄清代码

请您参考如下方法:
你可以尝试类似的东西
def removeWidget(self):
widget = self.widgets.pop()
widget.widgetFrame.pack_forget()
print(self.widgets)
