#82374 — Text Code(from 'Getting Started in Beautiful Soup' re: cd Soup , returns 'Syntax Error, invalid syntax'

At the start of Chapter 3 of 'Getting Started in Beautiful Soup' it has said to create a html file, 'ecological 

pyramid.html' - which I have already done re:
----------------------------------------------------------------------------
<html>
<body>
<div class="ecopyramid">
<ul id= "producers">
<li class="producers">
<li class="producerlist">
<div class="name">plants</div>
<div class="number">100000</div>
</li>
<li class="producerlist">
<div class="name">algae</div>
<div class="number">100000</div>
</li>
</ul>
<ul id ="primaryconsumers">
<li class="primaryconsumerlist">
<div class="name">deer</div>
<div class-"number">1000</div>
</li

<div class="number">50</div>
</li>
</ul>
</body>
</html>
----------------------------------------------------------------------------
and ran it okay in 'Explorer', and text then says to save it to a folder named 'Soup' which I have done. 
On the next page (30) it says to navigate to that folder with the following  code to the python console :-
 
cd Soup

however console rejects that code with the following return: - 
----------------------------------------------------------------------------
Python 2.7.6 (default, Nov 10 2013, 19:24:18) [MSC v.1500 32 bit (Intel)] on win

Type "help", "copyright", "credits" or "license" for more information.
>>> cd Soup
  File "<stdin>", line 1
    cd Soup
          ^

Thank you for reading, hope you can help.

You're probably supposed to type that in your command-line console (Similar to a Linux terminal), not your Python console.  "cd" is a command-line console command.

Please give your environment when starting a new thread.  Python version 
and OS version.  In this case, I'm guessing Windows, because I have to 
guess something to give a meaningful answer.

cd is not a Python "command", it's a   cmd command.  In other words, you 
type that in your DOS box before starting Python.

You mean like how he quoted his Python startup line, thus telling you
Python version, word size, and the fact that it's win32?

Granted, it would be nice to have that up front, rather than buried
deep in the text, but the information _is_ there.

Right of course.  My eyeballs didn't happen to scan that far to the 
right.  I was looking for drive letters or backslashes, or other clues, 
but missed the three-letter one "win" or for that matter the "MSC" one, 
which wouldn't actually have been conclusive.

Thanks Guys 
This book keeps swapping from the Python console to the Windows - without telling you, but it is the only book out there on 'Beautiful Soup' so I have got to put up with it. There's more problems with it, but I will start a new thread in regard of, I don't know if its related to the above or not. 
Yours

You may be able to recognize the consoles by their prompts. Python's
console is probably marked with ">>>" or "ipy>" or something, and the
Windows prompt most likely would have a path followed by ">"  (eg
"C:\>"). If the book's followed this convention, then you should be
able to figure things out easily enough once you get used to it.
Otherwise, look at the syntactic style: Windows command line, like
most command shells, uses a basic structure of command and arguments
separated by spaces, while Python uses a lot more symbols and
structural layout characters. But now we're getting into heuristics,
and there are some commands that work equally in Python and in Windows
(and do different things).
