Download attachment from mail using python

问题

I have multiple emails that contain an attachment. I would like to download the attachment for unread emails and with a specific subject line.

for example, I got an email that has a subject "EXAMPLE" and contains an attachment. So how it would be Below code, I tried but it is not working" it's a Python code

#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)

Here's a python (>=3.6) script to download attachments from a Gmail account. Make sure you check the filter options below.

import os
from imbox import Imbox # pip install imbox
import traceback

# enable less secure apps on your google account
# https://myaccount.google.com/lesssecureapps

host = "imap.gmail.com"
username = "username"
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):
        try:
            att_fn = attachment.get('filename')
            download_path = f"{download_folder}/{att_fn}"
            print(download_path)
            with open(download_path, "wb") as fp:
                fp.write(attachment.get('content').read())
        except:
            pass
            print(traceback.print_exc())

mail.logout()
