【问题描述】：

*此代码可帮助您预订座位，但无法显示已占用一次。我无法理解如何存储这些座位并将它们显示为已占用。 在运行此代码之前，请在您的设备上安装 tkinter *

from tkinter import *
def changeColor(btn):
    global c
    # Use your bg argument instead of highlight background
    btn.configure(highlightbackground='#ff0800')

root.mainloop()

如果我们可以使用 mysql 来存储选择或占用的按钮，我猜也会有所帮助

【问题讨论】：

请将此代码缩减为minimal reproducible example。我们没有 40 个按钮，只有两三个就足以说明问题了。

【参考方案1】：

我不熟悉MySql，但是你可以存储占用座位的名称如下：

occupied = set()
def changeColor(btn):
    global c
    # Use your bg argument instead of highlight background
    btn.configure(background='#ff0800')
    occupied.add(str(btn))
    print(occupied)

【讨论】：

但这只有在我点击一个按钮后才会起作用。有什么方法可以在不点击任何东西的情况下看到被占用的地方
