Answer 2

imap_host = 'imap.gmail.com' 
mail = imaplib.IMAP4_SSL(imap_host) 
mail.login(user,passw) 
mail.select("Inbox") 
mail = get_unseen(mail) 

result, data = mail.uid('search', None, 'UNSEEN') 
uid_list = data[0].split() 
print len(uid_list), 'Unseen emails.' 

for i in range(len(uid_list)): 
    email_uid = uid_list[i] 
    res, dat = mail.uid('fetch', email_uid, '(RFC822)') 
    raw_email = dat[0][1] 
    msg = email.message_from_string(raw_email) 

    print '' 
    print 'New email:\n' 
    print i,'UID:', email_uid, 'Sender:', email.utils.parseaddr(msg['From'])[0],email.utils.parseaddr(msg['From'])[1]  
    print 'Subjct:',msg['Subject'] 
    print 'Message: ' 
    print get_body(msg) 
    attach_list = get_attach_list(msg) 
    print len(attach_list),'Attachments:',attach_list 
    get_attach(msg) 

def get_body(msg): 
    for part in msg.walk(): 
     content_type = part.get_content_type() 
     if content_type == 'text/plain' or content_type =='text/html': 
      payload = part.get_payload(decode=True) 
      if payload: 
       print payload 
    return 

def get_attach_list(msg): 
    attach_list=[] 
    for part in msg.walk(): 
     filename = part.get_filename() 
     if filename: 
     attach_list.append(filename) 
    return attach_list 

def get_attach(msg): 
    for part in msg.walk(): 
     filename = part.get_filename() 
     if filename: 
      fp = open(filename,'wb') 
      fp.write(part.get_payload(decode=True)) 
      fp.close() 
    return 

所以，基本上你要做的就是通过完整的邮件走路，并寻找附件，然后用get_payload（），你下载的附件。
