entities = YourKind.all().fetch(20)

dict_of_entities = dict((str(entity.key()), {'name': entity.name, 'size': entity.size}) for entity in entities)

# or

list_of_entities = [{'key': str(entity.key()),
                     'name': entity.name,
                     'size': entity.size} for entity in entities)]

You can use the low-level datastore interface found in google.appengine.api.datastore (and documented there, too). This provides an interface to the datastore that lets you work with dictionaries instead of models.
