Probably the simplest thing to do is something like:

Create a file 'myserver.py' in a directory with some .html
(or .htm) files you want to see.  Let's pretend one of the
html files is named 'slithey.html'.  Here is the body (no
indentation in file) of 'myserver.py':

     import SimpleHTTPServer
     SimpleHTTPServer.test()

Open a command line in your OS, go to the directory you chose above,
and on that command line type the python magic incantation to run
a python program.

As the program starts, it will mention a port.  For the purposes of
this recipe, I'll pretend the port number printed out is "8123".
While your program is still running, open a browser.
Into the browser, enter one of the following URLs.

     http://127.0.0.1:8123/slithey.html
     http://localhost:8123/slithey.html
Or, if you know the name of your computer, you can substitute that
for "localhost".  Similarly, if you know the TCP/IP address of your
computer, substitute it for 127.0.0.1

localhost and 127.0.0.1 are "magic" ways to refer to your own computer.
Neither should be using your actual internet connection (but you
might get a cute page in firefox if you get the port number wrong).

If you don't know your IP number, you can browse to:
     <http://www.lawrencegoetz.com/programs/ipinfo/>

which creates a page with your number (every connection needs to
know the number of the other side in order to reply).

    <http://www.wown.com/j_helmig/tcpip.htm>
explains some basic tcp/ip address stuff (but operational stuff there
is for Microsoft Windows).
