My favorite reference for RasPi GPIO hardware and programming is the RasPi Hardware Wiki: http://elinux.org/RPi_Low-level_peripherals

It has programming examples in various languages, including Python: http://elinux.org/RPi_Low-level_peripherals#Python

The Wiki indicates that you need to "sudo" in order to access the GPIOs. Most of the examples require "sudo" in some form because the /dev/mem device driver normally requires that you run as root. For more information on this, see the Wiki and the element14 discussion: http://www.element14.com/community/message/60894/l/anyone-know-how-to-access-raspi-gpio-without-sudo#60894
