In a simple application, you can simply examine req.uri in your
handler() function, and dispatch based on that. Here's an untested

from mod_python import apache, util

def handler(req):
    # req.uri = the path portion of the URI.
    # "http://www.mycorp.org/myapp/topic.htm?a=3" -> "/myapp/topic.htm"
    page = req.uri
    if page == "/myapp/submit.htm":
        return submit(req)
        return view(req)

def view(req):
<form action='/myapp/submit.htm' method='POST'>
Please enter your name:
<input type='text' name='name' size='20' />
    return apache.OK

def get_params(req):
    final = {}
    params = util.FieldStorage(req, 1).list
    if params is not None:
        for p in params:
            final[p.name] = p.value
    return final

def submit(req):
    params = get_params(req)
    req.write("Thank you, %s!" % params.get('name'))
    return apache.OK
