发送带有 3 个不同附件的单个电子邮件 python 3
Sending single email with 3 different attachments python 3
我只想发送一封包含 3 个 csv 文件附件的电子邮件。当我到达 运行，尝试我在此处找到的解决方案时，它给了我一个 BIN 文件而不是 3 个文件。或者，尝试另一种解决方案，它只会发送 3 个文件中的最后一个。当我 运行 下面的代码时，它给我 TypeError: add.header() takes 3 positional arguments but 4 were given.
我知道这可以通过一个函数来完成，但我不确定如何让它将所有三个文件都拉入其中。我花了很多时间试图弄清楚。
把它贴在这里是我最后的选择。感谢您在寻找解决方案方面提供的任何帮助。

如您所见，您需要指定 base64 编码的文件名。
您还对文件进行了三次迭代。
一个for循环用于遍历列表、集合、数组等。一个for循环（因为所有附件都在一个列表中）应该足够了。
