how to modify text in html form from python

Fri Oct 21 15:18:40 EDT 2005

PS: If my question is not clear, I am trying to "share" the form between the
client and server.

just as many sites out there allow you to modify existing data:
1) the server pops up a form with your data in it.
2) the client can modify it and submit.

I know this is a _basic_ question, sorry.
