[Tutor] Tutor Digest, Vol 51, Issue 23

[root]

Hi ,
	I AM TRYING FOR A PYTHON PROGRAM THAT WILL CHECK WHETHER {- PHP AND
MYSQL -} ARE INSTALLED ON lINUX OR NOT AND IF THEY ARE NOT INSTALLED
THEN THE SCRIPT WILL TO INSTALL IT.

for this I am doing

import sys
import os
import commands
import sys


	commands_hash = {}
	commands_hash['php'] = {}
	commands_hash['php']['title'] = "***********PHP**************"
	commands_hash['php']['value'] = "rpm -qa *php*"
	commands_hash['mysql'] = {}
	commands_hash['mysql']['title'] = "***********MYSQL**************"
	commands_hash['mysql']['value'] = "rpm -qa *mysql*"


this is checking whether PHP and MYSQL are installed but PLEASE TELL ME
HOW TO ENHANCE IT SO AS THE INSTALL IT IF NOT INSTALLED ALREADY.

Thanks

Jatinder Singh
