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

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).

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:

Web Programming in Python : CGI Scripts

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
