我是这个网站的新手和编程。现在我面临挑战：我必须使用Python 3.6.2将表单中的条目插入到MySQL表中。有问题的窗口是动态的，这意味着我可以在其中添加或删除字段（显然，数据库中的表格不会相应地修改）。
我真正需要的是从表单中捕获一些条目（并省略重复的条目，如＆＃34;确认密码＆＃34;和＆＃34;确认电子邮件＆＃34;），但也来自地址2（这是可选的。）
下面我粘贴我的代码（其中一些改编自本网站）。我省略了SQL查询，因为我不知道应该放在哪里。我需要的数据来自＆＃34; def create_window2()＆＃34;。
提前致谢。

答案 0 :(得分：0)
这应该让你开始，虽然显然还有更多工作要做。此程序使用实例对象/变量，因此您不会从函数返回值，因为实例对象可在类中的任何位置使用。此外，我使用grid（）而不是pack（），但这只是个人偏好。
