如何使用python从电报邮件中获取图像url

import imaplib
import email
import re

mail = imaplib.IMAP4_SSL('imap.example.com')
mail.login('your_email@example.com', 'your_password')
mail.select('inbox')

result, data = mail.search(None, 'FROM', 'telegram.org')

for num in data[0].split():
    result, data = mail.fetch(num, '(RFC822)')
    raw_email = data[0][1]
    email_message = email.message_from_bytes(raw_email)
    
    for part in email_message.walk():
        if part.get_content_type() == 'image/jpeg':
            url = re.search("(?P<url>https?://[^\s]+)", str(part))
            if url:
                print(url.group("url"))

mail.logout()
