您可以将空列表分配给窗格以使其为空
Panes = []
但是您将永远失去所有添加的窗格。
也许您应该为键盘窗格制作单独的列表，而不是仅绘制此列表。
编辑：
顺便一提：
myScreen您对两个屏幕都使用一个变量- 运行myScreen = Screen(...)时创建新屏幕但无法访问前一个屏幕。
用来Screen = pygame.display.set_mode((1366,768), 0, 32); self.screen = Screen清屏是浪费时间和记忆。你只需要self.screen.fill((white))
您在某些函数中使用Screenname 作为类名和变量。您可能会意外发生名称冲突。
编辑：
完整的工作示例代码看起来如何：
我使用一个self.screen，因此不会每次都创建/删除窗口。
您可以按“ESC”键显示/隐藏键盘。

- 类键盘
- 窗格有一个 event_handler
- 鼠标悬停时的窗格测试
- 鼠标悬停时窗格更改背景（黄色）
- 按下鼠标时窗格更改背景（红色）
- 点击屏幕上的 Q 键关闭键盘
- 当点击键 Q 时，键盘将自己的事件发送到主循环 - 通知键盘已关闭
