creating datasets that anyone can use for testing purposes. This allows the com-

munity to repeat results that others get without having to download custom data-

sets from an unknown source. The final section of this chapter helps you get and 

install the datasets needed for the examples.

Considering the Benefits of Python

To work with algorithms on a computer, you need some means of communicating 

with the computer. If this were Star Trek, you could probably just tell the computer 

what you want and it would dutifully perform the task for you. In fact, Scotty seems 

quite confused about the lack of a voice computer interface in Star Trek IV (see 

http://www.davidalison.com/2008/07/keyboard-vs-mouse.html

 for details). 

The point is that you still need to use the mouse and keyboard, along with a special 

language, to communicate your ideas to the computer because the computer isn’t 

going to make an effort to communicate with you. Python is one of a number of 

languages that is especially adept at making it easy for nondevelopers to commu-

nicate ideas to the computer, but it isn’t the only choice. The following paragraphs 

help you understand why this book uses Python and what your other choices are.
