The standard python json module only can convert json string to dict structures.
But I prefer to convert json to a model object strutures with their "parent-child" relationship.
I use google-gson in Android apps but don't know which python library could do this.
You could let the json module construct a dict and then use an object_hook to transform the dict into an object, something like this:
>>> import json
>>>
>>> class Person(object):
... firstName = ""
... lastName = ""
...
>>>
>>> def as_person(d):
... p = Person()
... p.__dict__.update(d)
... return p
...
>>>
>>> s = '{ "firstName" : "John", "lastName" : "Smith" }'
>>> o = json.loads(s, object_hook=as_person)
>>>
>>> type(o)
<class '__main__.Person'>
>>>
>>> o.firstName
u'John'
>>>
>>> o.lastName
u'Smith'
>>>
You could write your own serializer to make it work with json, but why not use pyyaml which supports it out of the box:
>>> import yaml
>>> class Foo:
... def bar(self):
... print 'Hello I am bar'
... def zoo(self,i):
... self.i = i
... print "Eye is ",i
...
>>> f = Foo()
>>> f.zoo(2)
Eye is 2
>>> s = yaml.dump(f)
>>> f2 = yaml.load(s)
>>> f2.zoo(3)
Eye is 3
>>> s
'!!python/object:__main__.Foo {i: 2}\n'
>>> f2 = yaml.load(s)
>>> f2.i
2
