installing python for windows xp

I downloaded the newest version of python and I can’t seem to install it.I’am sure that this has been posted before but I need help on knowing how to install python so that I can use yafray for some of my renders. Thanks

Isn’t it an installer?

you need python 2.5, not the newest. python is not backward compatible. http://www.python.org/download/releases/2.5.2/
