there are different points in time.
rendering the DTML happens on the server before the result is sent to the browser.
you may see what the browser has received w view/source or so.
then on the client (=browser) system a <form> is submitted
and the resulting request sent back to the server.
On the server, ZPublisher prepares a REQUEST object for you
and, since the url is your python script, ZPublisher calls it.
a DTML file's <form> does not call your script directly.

all the browser sends is strings.
You may tell ZPublisher to convert these strings
to something else by exploiting a little trick on the form variable names
(see again http://www.zope.org/Members/Zen/howto/FormVariableTypes,
also http://www.dieter.handshake.de/pyprojects/zope/book/chap3.html)
Or, you may convert by using _.int(), _.float etc as converters,
which unfortunately applies to simple values only.
writing your own converter is a bit trickier.
