将linux系统用户导入mysql表

下面这个程序实现的一个很简单的功能，读取passwd文件，将里面的用户信息写入到mysql里面，

具体代码如下：

 #!/usr/bin/python

 import pymysql
 import time

 '''

 CREATE TABLE `os_user` (
   `user` varchar(20) NOT NULL,
   `haspass` char(5) NOT NULL,
   `uid` int(10) NOT NULL,
   `gid` int(10) NOT NULL,
   `descuser` varchar(100) NOT NULL,
   `homedir` varchar(100) NOT NULL,
   `loginshell` varchar(100) NOT NULL,
   PRIMARY KEY (`uid`),
   UNIQUE KEY `unique_var` (`user`,`uid`)
 ) ENGINE=InnoDB DEFAULT CHARSET=utf8;

 '''

 try:
     conn = pymysql.connect(host='127.0.0.1',unix_socket='/tmp/mysql.sock',\
                            user='root',passwd='',db='pydb')
     cur = conn.cursor()
     f = open('passwd')

     try:
         for i in f.readlines():
             Tmplist = list(i.strip('\n').split(':'))
             sql = 'INSERT INTO os_user \
                   (user,haspass,uid,gid,descuser,homedir,loginshell) values \
                   (\'%s\',\'%s\',%s,%s,\'%s\',\'%s\',\'%s\')' % \
                   (Tmplist[0],Tmplist[1],Tmplist[2],Tmplist[3],Tmplist[4],Tmplist[5],Tmplist[6])
             cur.execute(sql)
             time.sleep(1)
             conn.commit()
             print 'Create user %s Successful..' % Tmplist[0]
     except pymysql.err.IntegrityError as e:
          print 'User %s exits.' % Tmplist[0]
          print 'Please check, Exit...'
     except Exception as e:
          print 'Error : %s ' % e

 except Exception as e:
      print 'Error : %s ' % e

 finally:
     cur.close()
     conn.close()
     f.close()
