There is a thread called "Starting Python" just above or near this one. Give it a try!
Python is available for many different Operating Systems, so you have to make sure you are downloading and installing the right version.
Hope you get inspired with Python. It is a relatively easy computer language to learn and read, that can do just about any application you can possibly program. There are a number of modules in the standard Python distribution to make web programming possible.
When you download python its easy just select what OS you have.
Python comes with an editor (well my one did Ver 2.5)
and you can use notepad to write you scripts just end the name in .py
