这是较大项目的一小部分.我只需要获取未读电子邮件并解析其标题.如何修改以下脚本以仅获取未读电子邮件？
conn = imaplib.IMAP4_SSL(imap_server)
conn.login(imap_user, imap_password)
status, messages = conn.select('INBOX')
if status != "OK":
print "Incorrect mail box"
exit()
print messages
如何将变量插入到我用python发送的html电子邮件中？我想要发送的变量是code.以下是我到目前为止的情况.
text = "We Says Thanks!"
html = """\

Here is your unique code to unlock exclusive content:<br>

如何在启动时加载rabbitmq配置以确认创建了代理对象(队列,交换,绑定,用户,虚拟主机,权限和参数).
根据rabbitmq文档,可以通过http://www.rabbitmq.com/management.html#load-definitions完成load_definitions
但我无法弄清楚如何使用它.有人会介意分享一个如何运作的例子吗？我在网上找不到任何例子.
谢谢

我可以打印密钥：
$ jq -r '.indices | keys[]'
plan
resource
user
我可以打印子值：
$ jq '.indices[] | .primaries.docs.count'
14208
1427143
104475
如何打印键和子值？
plan: 14208

1) 如何升级 postgres 扩展？
2）你如何安装特定的扩展版本？
在生产中，hstore 的版本已过时。
=> select * from pg_available_extensions where name ='hstore';
name | default_version | installed_version | comment
--------+-----------------+-------------------+--------------------------------------------------
hstore | 1.3 | 1.1 | data type for storing sets of (key, value) pairs
所有其他环境 hstore 已经是 1.3，所以我没有办法测试是否create extension hstore;是我所需要的。
我想先测试升级并通过 Docker 运行 Postgres 9.4.4
docker run --name some-postgres -e POSTGRES_PASSWORD=mysecretpassword -d postgres:9.4.4
docker run -it --rm --link some-postgres:postgres postgres:9.4.4 psql -h postgres -U postgres
但是 hstore 1.3 是默认版本
name | default_version | installed_version …我有一个看起来像这样的csv文件：
artist,year,id,video_name,new_video_id,file_root_name,video_type
,,,,,,

我花了最后两个小时试图解决这个问题.请帮助我在过去两个小时内尝试使用Google.没运气.我究竟做错了什么？
codes.txt的内容:
TKF6J-KXP6V-F499V-Q9XPC-7J6TZ;J9YCV-D4TH6-WWWWV-F2RM7-F63XZ;GXKCC-QDT34-3JRY4-TWKHX-R763Z;
myscript.py
import re
from sqlalchemy import *
string = open("codes.txt").readlines()
for item in string:
set = [item.split(";")]
print "success"
为什么它只打印一次"成功"？我希望它能为codes.txt中的项目数量打印成功.
我没有看到第三个论点.当我运行此命令时:
used_emails = [row.email for row
in db.execute(halo4.select([halo4.c.email],[halo4.c.email!='']))]
它说:
TypeError:select()最多需要2个参数(给定3个)
第三个论点在哪里？
