我需要使用Python脚本从邮件中下载传入的附件,而无需过去附件。
例如:如果此时(现在)有人发送邮件,则只将该附件下载到本地驱动器而不是过去的附件。
请任何人帮我使用python脚本或java下载附件。

inbox = outlook.GetDefaultFolder(6)
messages = inbox.Items
def saveattachemnts(subject):
for message in messages:
if message.Subject == subject and message.Unread or message.Senton.date() == today:
# body_content = message.body
