Does anyone know of any good resources for information on how to POST data from a HTML form over to a python script?

A:
For a very basic CGI script, you can use the cgi module. Check out the following article from the Python documentation for a very basic example on how to handle an HTML form submitted through POST:
Example from the above article:
#!/usr/bin/env python
import cgi
import cgitb; cgitb.enable() # for troubleshooting
print "Content-type: text/html"
print
print """
<html>
<head><title>Sample CGI Script</title></head>
<body>
<h3> Sample CGI Script </h3>
"""
form = cgi.FieldStorage()
message = form.getvalue("message", "(no message)")
print """
<p>Previous message: %s</p>
<p>form
<form method="post" action="index.cgi">
<p>message: <input type="text" name="message"/></p>
</form>
</body>
</html>
""" % message

I'm coming from a HTML / JS / php background and sort of confusing myself. What format is the above example? How would I point a browser to it?

@Meowmix: It's exactly like php, but using python. It is executed by your web server, and renders the HTML page with a simple form. When the form is posted back to the script, it simply renders back the posted message.

You can also just use curl on the command line. If you're just wanting to emulate a user posting a form to the web server, you'd do something like:
curl -F "user=1" -F "fname=Larry" -F "lname=Luser" http://localhost:8080
There are tons of other options as well. IIRC, '-F' uses 'multipart/form-data' and replacing -F with '--data' would use urlencoded form data. Great for a quick test.
If you need to post files you can use
curl -F"@mypic.jpg" http://localhost:8080
And if you have to use Python for this and not a command line, I highly recommend the 'poster' module. http://atlee.ca/software/poster/ -- it makes this really, really easy (I know, 'cos I've done it without this module, and it's a headache).
