python读取postgresql数据库并发送相关提醒邮件

代码如下：

#！/usr/bin/env python
import smtplib
from email.mime.text import MIMEText
import psycopg2
import datetime
from time import *

mail_host= "smtp.XXX.com"
mail_user= "XXX"
mail_pass=  "XXX"
mail_postfix="XXX.com"

def send_mail(to_list,sub,content):
me="Remind Email"+"<"+mail_user+"@"+mail_postfix+">"
msg = MIMEText(content,_subtype='plain',_charset='gb2312')
msg['Subject'] = sub
msg['From'] = me
msg['To'] = ";".join(to_list)
try:
server = smtplib.SMTP()
server.CONNECT(mail_host)
server.login(mail_user,mail_pass)
server.sendmail(me, to_list, msg.as_string())
server.close()
return True
except Exception, e:
print str(e)
return False

## 取本地时间与数据库项目时间作比较 ##
today=strftime('%Y-%m-%d',localtime())
today_date=datetime.datetime.strptime(today,'%Y-%m-%d')

## 与postgresql数据库链接 ##
pgdb_conn = psycopg2.CONNECT(database = 'test',user = 'username', password = '123456', host = '1.1.1.1')
pg_cursor = pgdb_conn.cursor()
sql_desc = "select * from tbl_product3"
pg_cursor.execute(sql_desc)
for row in pg_cursor:
date=row[0]
to_list=row[1]
sub=row[2]
content=row[3]
Other_date=datetime.datetime(date,'%Y-%m-%d')
delta=Other_date-today_date
if delta.days == 1:
send_mail(to_list,sub,content)

pg_cursor.close()
pgdb_conn.close()
