>>> import cgi
>>> form = cgi.FieldStorage()
>>> dir(form)
['FieldStorageClass', '_FieldStorage__write', '__contains__',
'__doc__', '__getattr__', '__getitem__', '__init__', '__iter__',
'__len__', '__module__', '__repr__', 'bufsize', 'disposition',
'disposition_options', 'done', 'file', 'filename', 'fp', 'getfirst',
'getlist', 'getvalue', 'has_key', 'headers', 'innerboundary',
'keep_blank_values', 'keys', 'length', 'list', 'make_file', 'name',
'outerboundary', 'read_binary', 'read_lines', 'read_lines_to_eof',
'read_lines_to_outerboundary', 'read_multi', 'read_single',
'read_urlencoded', 'skip_lines', 'strict_parsing', 'type',
'type_options']

The form is not a dictionary.
