Extracting email attachment when is_multipart() is False

[Davor Cengija]

I need to write a script which should extract the attachment from a text
file, which is saved as MIME mail message. Unfortunatelly,
Message.is_multipart() returns False so msg.get_payload() returns the
complete message. What I need is the attachment only. Is it possible to do
that with standard email package without the actual string level parsing?

This is how my file/message looks like:

====== start here ========
This is a multi-part message in MIME format.

------=_NextPart_000_0026_01C3B347.DBEA9660
Content-Type: text/plain;
 charset="us-ascii"
Content-Transfer-Encoding: 7bit

CONTENT

signature, etc

------=_NextPart_000_0026_01C3B347.DBEA9660
Content-Type: application/octet-stream;
 name="filename.csv"
Content-Transfer-Encoding: 7bit
Content-Disposition: attachment;
 filename="filename.csv"

10012;20031118;292.67;4
101;23;19.98;2;39.96
102;24;21.89;4;87.56

------=_NextPart_000_0026_01C3B347.DBEA9660--

====== end here ========

So, I obviously need this part only:

10012;20031118;292.67;4
101;23;19.98;2;39.96
102;24;21.89;4;87.56

Python 2.3.2 on windows.

Thanks and regards,
