this is the command you need to find out if you have python installed in your linux server
The Google Sitemap Generator is a Python script that creates a Sitemap for your site using the Sitemap Protocol. This script can create Sitemaps from URL lists, web server directories, or from access logs. In order to use this script you must have Python installed in your webserver.
Before Joinning Google Sitemap Generator, I had never heard of Python before. Much less aware if it was installed in my web server.
To find out if you have Python installed in your Linux server all you have to do is execute the following command at the shell prompt:
| which python |
For me - When I executed this command it displayed:
| /usr/bin/python |
You might get something different, but the idea is to see "python"
