python如何导入txt数据库？

#!/usr/bin/python

#coding=utf-8

import _mysql,sys,time

#读入数据函数

def add_data(id,name,created_time):

    try:

        conn=_mysql.connect('127.0.0.1','root','')

        conn.query("set names utf8")

        conn.query("insert into mysql.test3(%s,%s,%s) values('%s','%s','%s')"%('object_id','object_name','created',id,name,created_time))

        result=conn.use_result()

        conn.close()

    except _mysql.Error,e:

        print ("error %d:%s" % (e.args[0],e.args[1]))

        sys.exit(1)

if __name__ =="__main__":

    f= open("/opt/testdata/aaa.txt","r")

    time1=time.time()

    print time.ctime()

    #读出第一行数据，作为数据表的段名

    line=f.readline()

    content=line.strip().split(",")

    conn0=_mysql.connect('127.0.0.1','root','')

    print 'connection is builded succesfully'

    conn0.query("drop table if exists mysql.test3")

    conn0.query("create table mysql.test3(%s varchar(90),%s varchar(90),%s varchar(90))"%(content[0][1:-1],content[1][1:-1],content[2][1:-1]))

    conn0.close()

    #运用next函数，让for循环从第二行开始读数据

    next(f)

    for line in f:

       #做一些处理，让每一段分开，放置在一个列表中

       content=line.strip().split(",")

       add_data(id=content[0][1:-1],name=content[1][1:-1],created_time=content[2][1:-1])

    f.close()

    time2=time.time()

    print time.ctime()

    #计算导入数据的时间

    print 'importing time is %f'%(time2-time1)
