For those of you who are anything like me, you’re debating buying the textbook, or are borrowing an older version of the text book. If so, you will not have the CD required to install python. Have no fear, though! Here are some instructions.
First, you will need to get a copy of Python 2.5. Python is currently at 3.1.1, but for the purpose of this course we are using version 2.5 (which I believe is what is on the school versions). To get this, go here, and download the file “python-2.5.4.msi” that is for x86 processors. Open the file, install for all users, install in the default directory (although you are free to install where you like, I recommend going with the default directory to be safe. Python is also not a large install, so it won’t be using too much space). Select all of the features from the “Customize Python 2.5.4″ menu, and then click next. Python will install. There may be a program that needs to be validated in order for the install to work (this came up for me in Windows 7), just click yes. Now python should be installed in your Start Menu, and you will have access to the IDLE environment and python.
