python - 使用python从邮件下载附件

Question

我有多封包含附件的电子邮件。我想下载未读电子邮件的附件，并带有特定主题行。

例如，我收到一封电子邮件，主题为“EXAMPLE”，并包含附件。那会怎么样
下面的代码，我试过了，但是没有用”
这是Python代码

#Subject line can be "EXAMPLE" 
      for subject_line in lst_subject_line:    
             # typ, msgs = conn.search(None,'(UNSEEN SUBJECT "' + subject_line + '")')
             typ, msgs = conn.search(None,'("UNSEEN")')
             msgs = msgs[0].split()
             print(msgs)
             outputdir = "C:/Private/Python/Python/Source/Mail Reader"
             for email_id in msgs:
                    download_attachments_in_email(conn, email_id, outputdir)

谢谢你

我能找到的大多数答案已经过时了。
这是一个Python(> = 3.6)脚本，用于从Gmail帐户下载附件。确保检查以下过滤器选项。

import traceback

password = 'password'
download_folder = "/path/to/download/folder"

if not os.path.isdir(download_folder):
    os.makedirs(download_folder, exist_ok=True)
    
mail = Imbox(host, username=username, password=password, ssl=True, ssl_context=None, starttls=False)
messages = mail.messages() # defaults to inbox

for (uid, message) in messages:
    mail.mark_seen(uid) # optional, mark message as read

    for idx, attachment in enumerate(message.attachments):

            att_fn = attachment.get('filename')
            download_path = f"{download_folder}/{att_fn}"
            print(download_path)
            with open(download_path, "wb") as fp:

            print(traceback.print_exc())

mail.logout()
