python报错：AttributeError: 'function' object has no attribute 'Attachments'

目的：用python下载收件箱内指定发件人的邮件附件后读取，但总是报错:(

    outlook = Dispatch("Outlook.Application").GetNamespace("MAPI")
    # 获取收件箱所在位置
    inbox = outlook.Folders[""].Folders["收件箱"]

    Mail_Messages.Sort("[ReceivedTime]", True)  # 按照接受日期排序

    def mail():

            print(type(mail.ReceivedTime))
            print('主题：{}'.format(mail.Subject))

    Highrisk_BP.to_excel('D:\\email\\Highrisk_BP2020.xlsx')
            # 保存邮件中的附件，如果没有附件不会执行也不会产生异常
    attachment = mail.Attachments
    for each in attachment:
                   save_attachment_path = 'D:\\email\\attachment'  # 保存附件到当前路径
                   each.SaveAsFile(r'{}\{}'.format(save_attachment_path, each.FileName))
                   print('附件（{}）保存完毕'.format(each.FileName))


read_outlook_mailbox()

可能文件名和方法名重名了，检查之后修改即可。
