1.2 Installing Python

First you need to download the appropriate file for your computer from http://www.python.org/download. Go to the 2.0
link (or newer) and then get the windows installer if you use Windows or the rpm or source if you use Unix.
TheWindows installer will download to file. The file can then be run by double clicking on the icon that is downloaded.
The installation will then proceed.
If you get the Unix source make sure you compile in the tk extension if you want to use IDLE.
