Python imaplib download Gmail Text without downloading the full attachment

Question

I am using 'imaplib' in python to fetch the email from a Gmail account. But I just want to know the content of the email, the title of the attachment, but do not need to download the full attachment.

By default,

myGmail = imaplib.IMAP4_SSL(...)
....
(respCode, data) = myGmail.fetch(mailUid, 'RFC822')

will return the whole part of email, including the whole attachment encoded as text in the return data, which is sometimes huge and unnecessary.

I've searched over the internet and stackOverflow to find answer. Many of them mentioned to use

myGmail.fetch(mailUid, 'BODYSTRUCTURE')

to determined the email structure first, and then identify the part you want download. And I have also read the RFC 3501 doc about imap4 protocol, in which it mentioned that I can use

BODY[]<> to download the specific body part in Fetch command.

But I've tried many command in python imaplib like following:

(rCode, data) = myGmail.fetch(mailUid, 'BODY[0]')
(rCode, data) = myGmail.fetch(mailUid, 'BODY0')
(rCode, data) = myGmail.fetch(mailUid, 'BODY[TEXT]')

but all of them failed with error message:

error: FETCH command error: BAD ['Could not parse command']

So anyone can tell me how to use this command in python imaplib for Gmail?

And just for your reference, the BODYSTRUCTURE for above example email is:

(BODY 
 (
  (
    (
      ("TEXT" "PLAIN" ("CHARSET" "us-ascii") NIL NIL "QUOTED-PRINTABLE" 1742 33)
      ("TEXT" "HTML" ("CHARSET" "us-ascii") NIL NIL "QUOTED-PRINTABLE" 17976 485) "ALTERNATIVE"
    )
    (
      "IMAGE" "JPEG" 
      ("NAME" "image001.jpg") "<image001.jpg@01CD029F.6831C440>" "image001.jpg" "BASE64" 4070
    ) 
    "RELATED"
  )
  ("APPLICATION" "PDF" ("NAME" "SAC 2012.pdf") NIL "SAC 2012.pdf" "BASE64" 20638)
  "MIXED"
 )
 )

Thanks!!!

Just replace BODY[0] with (BODY[1]).
