Try this:

#!python3
# -*- coding: utf-8 -*-

import email
import os

SOURCE_DIR = 'email'
DEST_DIR = 'temp'

def extractattachements(fle,suffix=None):
    message = email.message_from_file(open(fle))
    filenames = []
    if message.get_content_maintype() == 'multipart':
        for part in message.walk():
            if part.get_content_maintype() == 'multipart': continue
            #if part.get('Content-Disposition') is None: continue
            if part.get('Content-Type').find('application/octet-stream') == -1: continue
            filename = part.get_filename()
            if suffix:
                filename = ''.join( [filename.split('.')[0], '_', suffix, '.', filename.split('.')[1]])
            filename = os.path.join(DEST_DIR, filename)
            fb = open(filename,'wb')
            fb.write(part.get_payload(decode=True))
            fb.close()
            filenames.append(filename)
    return filenames

def main():
    onlyfiles = [f for f in os.listdir(SOURCE_DIR) if os.path.isfile(os.path.join(SOURCE_DIR, f))]
    for file in onlyfiles:
        #print path.join(SOURCE_DIR,file)
        extractattachements(os.path.join(SOURCE_DIR,file))
    return True

if __name__ == "__main__":
    main()
