Python - version > 2.6 and < 3

I was reading a book on Python by Charles Severance while taking a course. To install the environment, use these:

1. http://www.pythonlearn.com/install.php
2. https://www.python.org/download/releases/2.7.5/ (use windows x86 msi installer)

The following 31 words are keywords in Python (only 31?)

and          del        from        not      while

as            elif        global      or        with

assert      else       if             pass     yield

break       except   import     print

class        exec      in            raise

continue   finally    is            return

def           for        lambda    try

What about raw_input? That seems to be a keyword and not listed here.
