接收outlook邮件时可以多条件过滤

在使用outlook接收邮件的时候，我们可能会遇到这种情况，需要对主题或者附件进行过滤，但是过滤条件可能不止一个，这时RPA的ioutlook函数，可能不是很好使，所以自己就根据源码对过滤进行了简单的升级和优化。

def recv_outlook(mail_account, mail_inbox='收件箱', sender_filter=None, subject_filter=None, attachments_filter=None,
                 attachment_path=None, mark_as_read=True, only_unread=True, top=1):
    '''
    :param mail_account: 邮箱账号
    :param mail_inbox: 收件箱名称
    :param sender_filter 发件人过滤条件
    :param subject_filter: 主题过滤条件
    :param attachments_filter: 附件过滤条件
    :param attachment_path: 附件路径
    :param mark_as_read: 标为已读邮件
    :param only_unread: 查找未读邮件
    :param top: 一次读取几封邮件
    :return: tuple（邮件对象列表，邮件状态, 附件列表）
    '''
    # 邮件列表
    mails = []
    num = 1
    file_names = []
    state = False

    inbox = ioutlook.get_inbox(mail_account, mail_inbox)
    if inbox:
        messages = inbox.Items

        if only_unread:
            messages = messages.Restrict('[UnRead] = True')  # 未读取的邮件

        messages.Sort("[ReceivedTime]", True)  # 收件时间倒序

        if not top:
            top = len(messages)

        # 循环未读邮件
        for message in messages:
            # 附件列表
            atts = []
            if num > top:
                break
