python2 concurrent monitoring of multiple source replication status messages

We used a multi-source environment, replication, and therefore write to view the status of the Python script, python 2.6.6 comes with the system, the message content is html format, interlaced color, the script is as follows:

# -*- coding: UTF-8 -*-
import smtplib
from email.mime.text import MIMEText
from email.header import Header
import datetime
import MySQLdb
date_end = datetime.date.today()
html_part1 = """
