能够在python Tkinter中发送电子邮件时更改地址

我是Python的初学者，在Stackoverflow开发人员的帮助下，我成功地构建了以下代码

它是一个随机会议主机选择器。你基本上选择一个论坛，选择一种类型的工程师，它会随机选择一个工程师主持会议

问题：我需要电子邮件部分的帮助。选择此人姓名后，您如何发送电子邮件？它需要能够使用下拉列表中的电子邮件更新toaddr。邮件正文也必须写“你好[姓名]，你是下一个[选择论坛]的主持人，而现在，它写的是“你好！”。！label3，你是下一任的会议主席”

---

对于电子邮件，您可以执行以下操作：

• 创建名称>电子邮件的字典。这假定所有名称都是唯一的
• 设置工程师文本时，存储工程师电子邮件
• 发送电子邮件时，使用存储的电子邮件地址并拆分名称以获得第一个名称
• 对于论坛名称，只需创建一个名称数组，并使用f变量选择索引

这是更新后的代码。请注意，我根据这些名称创建了一个虚假电子邮件列表。您需要手动创建此列表

我试图尽可能少地更改您的程序。为了回答您关于主机名标签字段的问题的第一部分，tkinter使用字典结构来存储小部件的属性。因此，您需要使用host_engineer['text']来检索标签小部件上的文本

既然你说你是Python新手，我真的建议你阅读列表和字典。字典非常有用，但是当你循环使用它们时要小心，不能保证顺序

因此，我添加了一个“论坛名称”列表“用作每个论坛用户字典的键。这就引出了你问题的第二部分。由于列表的顺序是固定的，它允许我们在用户界面上创建单选按钮时使用列表，从而可以使用所选单选按钮的值作为索引来查找所选论坛名称。然后，该名称可以用作forum_用户词典中的关键字

对于工程组也可以做同样的更改，但正如我所说的，我尽量保留您的代码

我试着尽可能少地改变你的计划。为了回答关于主机名标签字段的问题的第一部分，tkinter使用字典结构来存储小部件的属性。因此，您需要使用host_engineer['text']来检索标签小部件上的文本

既然你说你是Python新手，我真的建议你阅读列表和字典。字典是非常有用的，但是当你循环使用它们时要小心，顺序不能保证

出于这个原因，我添加了一个“论坛名称”列表，作为每个论坛用户字典的键。这就引出了你问题的第二部分。由于列表的顺序是固定的，它允许我们在用户界面上创建单选按钮时使用列表，从而可以使用所选单选按钮的值作为索引来查找所选论坛名称。然后，该名称可以用作forum_用户词典中的关键字

对于工程组也可以做同样的更改，但正如我所说的，我尽量保留您的代码

非常感谢@SuzukiBKing。你明白我的需要，解决了这个问题。我一定会采纳你的建议，更多地学习字典和列表。我现在正在浏览代码，试图理解更改，因为它与原始代码非常不同。再次感谢你。祝你一切顺利！再次感谢你。我把代码通读了一遍，现在明白了。使用类确实很有意义，也很简单。现在的问题是“抄送邮件无法发送给收件人。嗨。很高兴我能帮忙。我现在无法测试它，但我已经编辑了答案，将行“msg['CC']=ccaddr”更改为“msg['CC']=ccaddr”，这将解决您的CC问题谢谢。我试过了，但没用。我在网上搜索了一下，它说我们也需要添加这个“server.sendmail（fromaddr，（toaddr+ccaddr），text）”，但仍然不起作用。埃罗
