在python Tkinter中发送电子邮件时可以更改地址

分类：编程问答

如何解决在python Tkinter中发送电子邮件时可以更改地址

我是Python的初学者，在Stackoverflow类开发人员的帮助下，我设法构建了以下内容。

这是一个随机的会议主持人选择器。您基本上是选择一个论坛并选择一种工程师，然后它将随机选择一名工程师主持会议。

问题：我需要有关电子邮件部分的帮助。选择此人的姓名后，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。电子邮件正文还必须说“嗨[名称]，您是下一个[选择论坛]的主持人，而当前，它说”嗨。！label3，您是下一个“无”的会议主席” 

Secure

解决方法

对于电子邮件，您可以执行以下操作：

  • 创建名称词典>电子邮件。假设所有名称都是唯一的
  • 设置工程师文本时，请存储工程师电子邮件
  • 发送电子邮件时，请使用存储的电子邮件地址并拆分名称以获得名字
  • 对于论坛名称，只需创建一个名称数组，然后使用f变量选择索引

这是更新的代码。请注意，我根据名称创建了一个虚假电子邮件列表。您将需要手动创建此列表。

我试图尽可能少地更改您的程序。为了回答有关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。

由于您说过您是Python的新手，所以我真的建议您阅读有关列表和字典的内容。字典非常有用，但是在遍历字典时要小心，不能保证顺序！

由于这个原因，我添加了一个“论坛名称”列表，用作每个论坛中用户词典的键。这将我带到您的问题的第二部分。由于列表的顺序是固定的，因此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_users词典中的键。

可以对工程组进行相同的更改，但是正如我所说的，我试图保留尽可能多的代码。

就电子邮件地址而言，您可以创建一个字典，该字典使用用户名作为键并将电子邮件地址存储为值。请记住，字典键必须是唯一的。

我实际上建议您宁愿创建一个小型类对象“用户”。然后，用户名，电子邮件地址，初中级或高级级，他们所属的论坛等可以是该类的属性。与您当前的代码相比，这将是一个很大的变化，但是从长远来看，它将变得更加容易和清晰。如果您有兴趣查看它的外观，请参见以下内容：
