why not use 'eval' keyword for parsing json..
Here is an example.
*with 'eval' *
json_data ='''
{
"firstName": "John",
"lastName" : "Smith",
"age" : 25,
"address" :
{
"streetAddress": "21 2nd Street",
"city" : "New York",
"state" : "NY",
"postalCode" : "10021"
},
"phoneNumber":
[
{
"type" : "home",
"number": "212 555-1234"
},
{
"type" : "fax",
"number": "646 555-4567"
}
]
}'''
d = eval('('+json_data+')')
for key in d:
print(key, ':', d[key].__class__, d[key])
*Output:*
lastName : <class 'str'> Smith
age : <class 'int'> 25
phoneNumber : <class 'list'> [{'type': 'home', 'number': '212
555-1234'}, {'type': 'fax', 'number': '646 555-4567'}]
firstName : <class 'str'> John
address : <class 'dict'> {'postalCode': '10021', 'city': 'New York',
'streetAddress': '21 2nd Street', 'state': 'NY'}
