thinking aloud and off the top of my head , you could try the email
module (python docs)

import email

msg = email.message_from_file(xxx) (or email.message_from_string(xxx) )

then something like 

for part in msg.walk():  
     length =  len(str(part))
     fname = part.get_filename()
or

if msg.is_multipart( ):
    temp_payload = msg.get_payload()
    for x in range(len(temp_payload)):
        print temp_payload[x].get_content_type()
        print temp_payload[x].get_filename()
        print len(str(temp_payload[x]))

Remember any size you get  will be the size of the attachment whilst
its encoded into a mime object,  which won't be the same as the size
of the file on disk.

I'm not sure the above will work,  but its in the right ball park,  If
you don't have any luck post back and I'll look into it next time I'm
in the office and have python docs easily to hand.
