Question

我正在使用python IMAP4，并且能够登录并获取具有给定主题的那些电子邮件的UID列表，我正在尝试获取给定UID列表（主题，从和到）的电子邮件标头组件： / p>

for i in range(0, len(self.myUIDList)):
    print ("self.myUIDList[i]= ", self.myUIDList[i])
    typ, msg_data = self.mail.fetch(str(self.myUIDList[i]), '(RFC822)')
    for response_part in msg_data:
        if isinstance(response_part, tuple):
            print (" response_part= ", response_part)
            msg = email.message_from_string(str(response_part[1]))
            print ("msg = ", msg)
            for header in ['subject', 'to', 'from']:
                print ('%-8s: %s' % (header.upper(), msg[header]))

＃

来自stdOut消息是->

我需要的只是标题主题，从和到
