Python基于一个Inpu删除行

Question

我正在用Tkinter做一个GUI程序。你知道吗

程序接收CSV文件。然后有函数AddDeleteUpdate 我已经完成了add部分，但我也可以完成delete部分，但不知何故，我只想尝试通过列删除。例如，条目为：

2012-1221, Name Lastname, 

我想通过ID Number 2012-1221删除所有这些条目

我不能就这么做。这是我的密码：

请看我的delete部分。我可以删除一个条目，但我必须把所有的东西都拼出来，对用户来说这会是一个麻烦，对吧？我想通过ID number only删除条目来简化操作。感谢您的帮助。谢谢！你知道吗
