Question

以下是我为柜台提供的代码：

import mailbox
import pprint
f=open("results.txt","w")
mbox = mailbox.mbox('c:\documents and settings\student\desktop\mail\mail.mbox')
count = 0
for msg in mbox:
 pprint.pprint(msg._headers, stream=f)

  if "('Delivered-To', 'example@example')" in msg:
   count += 1
f.close()

此代码生成一个txt文件，看起来像这样，但是有一组又一组的电子邮件标题：

[('X-GM-THRID', '1484400558228312046'),
('X-Gmail-Labels', 'Sent'),

但是，我想计算标题“（'Delivered-To'，'example@example.com'）”出现在文本文件中的次数。我在我的代码中包含了一个计数但是我不确定它是否正确。另外，如果它是正确的，我如何打印txt文件末尾的计数？感谢

您似乎混淆了包含字符串的字符串的元组。

循环遍历mbox对象时，您将获得mboxMessage个实例，这是email.message.Message class的子类。您可能希望在此处使用该界面：

for msg in mbox:
    if msg['Delivered-To'] == 'example@example':
        count += 1

我的计数是否有效，如何在txt文件中打印计数？蟒蛇
