json.dumps

default

json.loads

objec_thook

boy1 = boy('Will', 20)

#default method for decode
def boydefault(obj):
if isinstance(obj, boy):
return {'name': obj.name, 'age': obj.age}
return obj;

def boyhook(dic):
print('test')
if dic['name']:
return boy(dic['name'], dic['age'])
return dic

boy_encode_str = json.dumps(boy1, default=boydefault)
new_boy = json.loads(boy_encode_str, object_hook=boyhook)
print(boy_encode_str)
print(new_boy)
