本文主要是针对统计数据库中数据，并将数据存在Excel中，最后通过邮件将Excel发送给指定用户；直接上代码。
一、日志配置文件 Logger.conf
############################################
[loggers]
keys = root,example01,example02
[logger_root]
level = DEBUG
handlers = hand01,hand02
[logger_example01]
handlers = hand01,hand02
qualname = example01
propagate = 0
[logger_example02]
handlers = hand01,hand03
qualname = example02
propagate = 0
############################################
[handlers]
keys = hand01,hand02,hand03
[handler_hand01]
class = StreamHandler
level = DEBUG
formatter = form01
args = (sys.stderr,)
[handler_hand02]
class = FileHandler
lever = DEBUG
formatter = form01
args = ('./Result_count.log','a')
[handler_hand03]
class = handlers.RotatingFileHandler
lever = INFO
formatter = form01
args = ('./Result_count.log','a',10*1024*1024,5)
############################################
[formatters]
keys = form01,form02
[formatter_form01]
format = %(asctime)s %(filename)s[line:%(lineno)d] %(levelname)s %(message)s
datefmt = %Y-%m-%d %H:%M:%S
[formatter_form02]
format = %(name) -12s: %(levelname) -8s %(message)s
datefmt = %Y-$m-%d %H:%M:%S
二、读取配置文件的程序：Log.py
#!/usr/bin/python
#encoding=utf-8
import logging.config
logging.config.fileConfig("Logger.conf")
def debug(message):
logging.debug(message)
def warning(message):
logging.warning(message)
def info(message):
logging.info(message)
三、连接数据库并将统计结果存成Excel
#!/usr/bin/python
# -*- coding:utf-8 -*-
'''
方法：通过pymsql模块连接mysql数据库，然后通过游标cursor查询SQL语句将结果存储在Excel文件中，其中Excel的生成使用xlwt实现的。

def WritToExcel():

logging.info(u"#将字段名写入到EXCEL表头；")
