What have you tried ? ;-)

def form_to_dict(form):
    out_dict = {}
    for entry in form:
        out_dict[entry] = form[entry].value
    return out_dict

UNTESTED AND FROM MEMORY
If it doesn't work - try reading the manual to see what I did
wrong.....

At the cost of clarity ? Not a worthwhile trade off. Explicity delet
variables you have finished with instead.

form = cgi.FieldStorage()
formdict = form_to_dict(form)
del form
