python 中的 tkinter 计算器
tkinter calculator in python
我刚开始使用 tkinter 和 python，我正在尝试创建一个 GUI window 东西来计算约会之夜的总费用，有不同的旅行、娱乐选项等。我有两个主要问题：
1. 如果用户尝试输入提示，则什么也不会发生。不过，只要用户不尝试留下餐厅小费，该程序就可以正常工作。我试过重新格式化，但我似乎无法弄清楚为什么我的小费编码方式不起作用。如果选择了餐厅选项，则只应添加小费。
2. 这个错误可能比较简单，但我不知道如何编写正确的 "quit" 按钮。我有几行代码，这是我在网上搜索解决方案后尝试制作退出按钮的代码，但我似乎仍然缺少一些东西。
代码有点多，不过我会把它贴在这里。我感谢任何建议或反馈:)

此外，对于我在整个过程中提出的奇怪评论，我深表歉意。我删除了大部分，但是当我做这个的时候我很累，我觉得一切都很有趣。
当我 运行 编码时，我看到错误消息，其中显示问题出在哪里以及问题是什么。您应该阅读它并思考这一行有什么问题。您还应该添加有问题的错误消息。
Exception in Tkinter callback

错误显示行
before_tax = travel_result.get() + entertainment_result.get() + dinner_result.get + ((int(tip_result.get()) / 100) * dinner_result)
并且在这一行中，您在第一个 dinner_result 中忘记了 ()，在第二个 dinner_result
中忘记了 .get()
应该是
before_tax = travel_result.get() + entertainment_result.get() + dinner_result.get() + ((int(tip_result.get()) / 100) * dinner_result.get())
现在显示 Restarunt
的正确结果
至于按钮 Quit - 你在 app_window.destroy()
