我想打印沒有附件的郵件

Question

當我運行這段代碼時，它以unicode形式打印附件中的數據，所以我想避免打印附件，我只想打印郵件正文附件。

import imaplib 
import email 

def extract_body(payload):# "want to download withut attachments" 
    if isinstance(payload,str): 
     return payload 
    else: 
     return '\n'.join([extract_body(part.get_payload()) for part in payload]) 

conn = imaplib.IMAP4_SSL("imap.gmail.com", 993) 
conn.login("tryntest@gmail.com", "password") 
conn.select(mailbox='INBOX',readonly=False) # [Gmail]/Spam 
typ, data = conn.search(None, 'ALL') #attributes :::UNSEEN,SEEN ALL 
f = open("Text_Email_imap1.txt","w") 
try: 
    for num in data[0].split(): 
     typ, msg_data = conn.fetch(num,'(RFC822)') 
     for response_part in msg_data: 
      if isinstance(response_part,tuple): 
       msg = email.message_from_string(response_part[1]) 
       subject=msg['subject']     
       print(subject) 
       f.write(subject+'\n\n\n\n') 
       payload=msg.get_payload() 
       body=extract_body(payload) 
       print(body) 
       f.write(body+'\n\n\n\n\n') 
     #typ, response = conn.store(num, '+FLAGS', r'(\Seen)') 
finally: 
    try: 
     conn.close() 
    except: 
     pass 
    conn.logout()

for part in mail_message.walk():  #Uses walk() method to make depth first search of mail parts/sub-parts 
     content_disposition = part.get("Content-Disposition",None) #get the value of keyword content disposition 
     print content_disposition 
     if content_disposition == None: 
      f.write(str(part.get_payload())) 
     else: 
      pass
