How do I access 'Beautiful Soup' on python 2.7 or 3.4 , console or idle versions.

[Simon Evans]

I am new to Python, but my main interest is to use it to Webscrape. I have downloaded Beautiful Soup, and have followed the instruction in the 'Getting Started with Beautiful Soup' book, but my Python installations keep returning errors, so I can't get started. I have unzipped Beautiful Soup to a folder of the same name on my C drive, in accordance with the first two steps of page 12 of the aforementioned publication, but proceeding to navigate to the program as in step three, re: "Open up the command line prompt and navigate to the folder where you have unzipped the folder as follows:
cd Beautiful Soup
python setup python install "

This returns on my Python 27 :
>>> cd Beautiful Soup
File "<stdin>",line 1
cd Beautiful Soup
           ^
SyntaxError: invalid syntax
>>>

also I get:
>>> cd Beautiful Soup
SyntaxError: invalid syntax
>>>

to my IDLE Python 2.7 version, same goes for the Python 3.4 installations. 
Hope someone can help. 
Thanks in advance.
