使用python打印电子邮件正文

Question

我正在尝试使用python打印收件箱中特定电子邮件的正文，但它似乎并不只是打印电子邮件的正文，而是打印我相信的整个标题

以下是我尝试过的（注意：我的代码可能完全错误）：

import imaplib, email 
  
user = 'myemail@gmail.com'
password = 'mypassword'
imap_url = 'imap.gmail.com'
  
# Function to get email content part i.e its body part 
def get_body(msg): 
    if msg.is_multipart(): 
        return get_body(msg.get_payload(0)) 
    else: 
        return msg.get_payload(None, True) 
  
# Function to search for a key value pair  
def search(key, value, con):  
    result, data = con.search(None, key, '"{}"'.format(value)) 
    return data 
  
# Function to get the list of emails under this label 
def get_emails(result_bytes): 
    msgs = []
    for num in result_bytes[0].split(): 
        typ, data = con.fetch(num, '(RFC822)') 
        msgs.append(data) 
  
    return msgs 
  
con = imaplib.IMAP4_SSL(imap_url)  
  
con.login(user, password)  
 
con.select('Inbox')  

msgs = get_emails(search('FROM', 'notify@protonmail.ch', con)) 
print(msgs)

这就是我得到的：
