For simple HTML generation, you can look into the htmlgen module 
(http://starship.python.net/crew/friedrich/HTMLgen/html/main.html) -- 
it's a little dated, but should be able to handle basic needs like this. 
 You can use it to generate the appropriate HTML tag for that form 
element, and then substitute your new element for the existing one.

In order to find the necessary tags, you can use one of the HTML parsers 
that's already distributed with Python.  Check out the htmllib and 
HTMLParser modules.  

I've never done HTML generation in Python myself, so I can't offer more 
specific pointers, but hopefully this will be enough to get you started 
in the right direction.
