Show subject for unseen IMAP mails

This python script handles MIME encodings and outputs everything in utf-8.
I use it with conky in spectrwm bar.

import imaplib
from email.header import decode_header

mail = imaplib.IMAP4_SSL('imap.gmail.com') # your imap server goes here
mail.login('example@gmail.com', 'password')
mail.select('INBOX', readonly=True)
typ, new = mail.search(None, "UNSEEN")
new = new[0].split()

if (len(new) > 0):
  res = list()
  for msg in new:
    typ, data = mail.fetch(msg, '(BODY[HEADER.FIELDS (SUBJECT)])') # FROM, DATE, etc
    data = data[0][1].strip()
    decoded = decode_header(data[9:])[0] # "Subject: " is 9 characters long
    text = decoded[0].replace("\r\n", "")
    if (decoded[1] != None):
      text = unicode(text, decoded[1])

    text = text[:20].strip() # Cut off first 20 characters from subject
    res.append(text.encode('utf-8'))
  
  print ', '.join(res)
