python poplib从电子邮件中获取标头

Question

这是我的actula代码：

import poplib, sys, re, threading, time, Queue
from email import parser

    Mailbox = poplib.POP3(pop3, '110')
    Mailbox.user(username)
    Mailbox.pass_(password)
    numMessages = len(Mailbox.list()[1])
    for i in range(numMessages):
            fullemail = ''
            fullemail = '\n'.join([msg for msg in Mailbox.retr(i+1)[1]])
            msg = parser.Parser().parsestr(fullemail)
            for part in msg.walk():
                    print part.get_payload(decode=True)

打印part.get_payload（decode = True）打印电子邮件正文，如何打印电子邮件标题？

Answer 1

items() / email.message.Message对象的方法email.message.EmailMessage可能有用：

for t in msg.items():
    print(t)

t是一个像这样的元组(key,value).
