Json pickle will do the trick : http://jsonpickle.github.io/
## import lib
import jsonpickle
## create class
class Thing(object):
def __init__(self, name):
self.name = name
## create class instance
obj = Thing('Awesome')
## from obj to json string
frozen = jsonpickle.encode(obj)
## from json string to obj
thawed = jsonpickle.decode(frozen)
