自学教程：python使用imap-tools模块下载邮件附件的示例

from imap_tools import MailBoxwith MailBox("imap服务器名").login("账号", "密码") as mailbox:    for msg in mailbox.fetch(limit=2,reverse=True):  # 我这里为了避免读取全部的邮件,加上了limit=2的匹配参数,读取两封邮件,按照最新接收的次序排序,进行测试;         for att in msg.attachments:  # msg为上一行取得的全部邮件            if att.filename:    # 如果附件的文件名不为空                att_data = att.payload # 获得附件的内容                f = open(att.filename,'wb') # 用二进制打开,一般邮件附件都是二进制的.                f.write(att_data)                f.close()
