python常用脚本以及问题跟踪

1.时间操作
//获取当前时间格式是%Y-%m-%d %H:%M:%S
currTime = time.strftime('%Y-%m-%d %H:%M:%S',time.localtime(time.time()))
//获取前一天日期格式为%Y-%m-%d
yesterday = datetime.date.today() - datetime.timedelta(days=1)
//获取前一个小时日期
yesterday = (datetime.datetime.now() - datetime.timedelta(hours = 1)).strftime("%Y-%m-%d %H:%M:%S")

2.mysql 操作

#!/usr/bin/python
#coding=utf-8
import MySQLdb
import datetime
import MailUtil
import time
try:
   connection = MySQLdb.connect(user="entdb",passwd="dm6db+1de@v",host="192.168.32.47",db="miss8")
except:
   print "Could not connect to MySQL server."
   exit( 0 )

print "----------------------------贵圈新闻数据流 check start------------------------------"
mailto_list=['xubaolong@iminer.com','yueyaobiao@iminer.com']
try:
        while True:
                cursor = connection.cursor()
                currTime = time.strftime('%Y-%m-%d %H:%M:%S',time.localtime(time.time()))
                #两小时前时间
                two_hours_ago = (datetime.datetime.now() - datetime.timedelta(hours = 2)).strftime("%Y-%m-%d %H:%M:%S")
                #明星和电影前一天微指数抓取
                cursor.execute( "SELECT count(1) from gquan_article_info where crawl_time>'"+str(two_hours_ago)+"'" )
                results = cursor.fetchall();
                count = 0
                for row in results:
                        count = row[0]

print "INFO\t当前时间: " + str(currTime) + "\t前两小时抓取数量是:" +str(count)

if count == 0:
                        tag = MailUtil.send_mail(mailto_list,'贵圈新闻数据流出现问题两小时之内没有数据','贵圈新闻数据流出现问题，请检查(47 数据库gquan_article_info)请尽快修复!!!!!!')
                        if tag:
                                print "ERROR\t当前时间：" + str(currTime) + "\t贵圈新闻数据流出现问题\t邮件发送成功"
                        else:
                                print "ERROR\t当前时间: " + str(currTime) + "\t贵圈新闻数据流出现问题\t邮件发送失败"
                else:
                        print "INFO\t当前时间：" + str(currTime) + "\t贵圈新闻数据流一切正常\t无须发送邮件"
                cursor.close()
                print "INFO\t当前时间：" + str(currTime) + "\t小e需要休息一小时!!!!!!"
                #睡一个小时
                time.sleep(1 * 60 * 60 )
except:
   print "Exception"
   exit( 0 )
print "----------------------------贵圈新闻数据流 check over------------------------------"

3.异常跟踪

Python 数据库连接的时候，报异常：ImportError: No module named release

Linux Fedora, CentOS系统：yum install MySQL-python 即可

4.mysql操作获取数量

#获取[昨天电影热度值符合规范]的数量
   cursor.execute( "select count(*) from domain_movie_hot_records where record_date = '"+str(yesterday)+"' and news_num > 0" )
   result = cursor.fetchone();
   yesterday_movie_correct_hot_count = result[0]
