[root@103-c7 first]# cat con.py
import MySQLdb
#db=MySQLdb.connect(host='192.168.10.104',user='root',password='123456',db='mysql')
db=MySQLdb.connect('192.168.10.104','root','123456','mysql')
cursor=db.cursor()
cursor.execute('select host,user,password from user')
result=cursor.fetchall()

for row in result:
        host=row[0]
        user=row[1]
        password=row[2]
        print 'user=%s,host=%s,password=%s' %(user,host,password)

#print result
cursor.close()
db.close()
