What is it you're trying to accomplish, Elaine? There are a number of
ways to write a Web server in Python, but how you intend to use that
server will determine which ways are most appropriate.

Probably the easiest HTTP server to write in Python is:

import SocketServer
import SimpleHTTPServe r

handler_class = SimpleHTTPServe r.SimpleHTTPReq uestHandler
ss = SocketServer.TC PServer( ('', 80), handler_class)
ss.serve_foreve r()

which will run a Web server, serving up files from the current
directory (the one from which you ran the program above). Run the
program, and visit http://localhost/ to see your server in action.

But chances are that's not what you need. You'll find the folks on
this list are tremendously helpful, but aren't much use unless you're
clear about what your end-goals are. Please elaborate!

Erm, it sounds like you're thinking about Internet Protocol (IP)
addressing, which is more fundamental than HTTP. TCP and IP are the
foundational protocols upon which HTTP is built; but so are FTP,
telnet, SMTP (e-mail), etc.

Google for "internet protocol tutorial" to learn more about IP
addresses.

OK. It would be nice to know a way in which somebody on another machine could
access the pages your example serves. Not necessarily a cute or convenient way,
but just a way. That would give me the foot-in-the-door feeling I'm looking for.

This worked well. Thanks

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 SimpleHTTPServe r
SimpleHTTPServe r.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.lawrencegoe tz.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).

unless there is firewalls in between you'll just need to browse to

http://your.ip.address.goes.here/ (the IP has to be a public one..)

i.e.

http://123.123.123.123/
