A simple example of the usage of JsonCls available at https://github.com/schlameel/JsonCls

JsonClsExample.py

class Character(JsonCls):
    name = Member()
    actor = Member()
    film = Member()

json_str = "{ 'name' : 'Dead Collector',
              'actor' : 'Eric Idle',
              'film' : 'Monty Python and the Holy Grail' }

character = Character().json(json_str)
print character.json()
# Prints:
# {'name': 'Dead Collector', 'actor': 'Eric Idle', 'film': 'Monty Python and the Holy Grail'}

print character.json(indent=2)
# Prints:
# {
#  'name': 'Dead Collector',
#  'actor': 'Eric Idle', 
#  'film': 'Monty Python and the Holy Grail'
#}
