Question

我希望能够有一个包含各种内容的配置文件。每封电子邮件都需要包含一个主题和一个正文，并带有新行。

例如：

[Message_One]
Subject: Hey there
Body: This is a test
      How are you?
      Blah blah blah

      Sincerely,
      SOS

[Message_Two]
Subject: Goodbye
Body: This is not a test
      No one cares
      Foo bar foo bar foo bar

      Regards

我如何使用Python作为配置文件在内容之间随机选择和/或通过其定义的名称（Message_One，Message_Two）获取？

Answer 1

也许是这样的：

from ConfigParser import ConfigParser
import random

conf = ConfigParser()
conf.read('test.conf')

mail = random.choice(conf.sections())
print "mail: %s" % mail
print "subject: %s" % conf.get(mail, 'subject')
print "body: %s" % conf.get(mail, 'body')

只需选择random.choice(conf.sections())的随机部分名称即可。 random.choice函数将从序列中选择一个随机元素 - sections方法将返回所有部分名称，即["Message_One", "Message_Two"]。然后，您可以使用该部分名称来获取所需的其他值。

#!/usr/bin/env python3
from re import match
from collections import namedtuple
from pprint import pprint
from random import choice

Mail = namedtuple('Mail', 'subject, body')

def parseMails(filename):
    mails = {}
    with open(filename) as f:
        index = ''
        subject = ''
        body = ''
        for line in f:
            m = match(r'^\[(.+)\]$', line)
            if m:
                if index:
                    mails[index] = Mail(subject, body)
                index = m.group(1)
                body = ''
            elif line.startswith('Subject: '):
                subject = line[len('Subject: '):-1]
            else:
                body += line[len('Body: '):]
        else:
            mails[index] = Mail(subject, body)
    return mails

mails = parseMails('mails.txt')
index = choice(list(mails.keys()))
mail = mails[index]
pprint(mail)

Mail(subject='Goodbye', body='This is not a test\nNo one cares\nFoo bar foo bar foo bar\nRegards\n')
