[python-win32] Updating webpage

[Antone]

I know this may not be a python question but I am using python to write cgi.
And I don't know how you have a button update the current page. Example
would be like a "shopping cart" on amazon.com web site. I am trying to get
some code were when the submit button is pressed it will remove or add a
line from the webpage and leave the rest as it was. Any help would be
appreciated.
