The automatic mapping of form data can useful in a simple, strictly 
controlled environment, but it's much better to use the standardized 
interface of the dictionary-like object req.form, as Jim suggests. This 
allows you to do simple, safe operations like:

for key in req.form.keys():
     do_stuff_with_key(key)

or:

if req.form.has_key('foo'):
     do_foo(req)

Note that req.form is *dictionary-like* and may still undergo changes to 
  make it behave more like a real dictionary. Try to use a recent 
version of mod_python to reduce incompatibilities.

Letting users name fields that are directly converted to top-level 
objects could cause severe namespace collisions, so don't even attempt 
that route.
