Parsing a json string:

>>> import json
>>> 
>>> jsonString = """[
...   {"firstName":"John", "lastName":"Doe"},
...   {"firstName":"Anna", "lastName":"Smith"},
...   {"firstName":"Angel", "lastName":"Cool"}
... ]"""
>>> 
>>> 
>>> print jsonString
[
  {"firstName":"John", "lastName":"Doe"},
  {"firstName":"Anna", "lastName":"Smith"},
  {"firstName":"Angel", "lastName":"Cool"}
]
>>> 
>>> data = json.loads(jsonString)
>>> 
>>> print data[2]['firstName']
Angel
>>> print data[2]['lastName']
Cool
>>> 
>>> type(data)
<type 'list'>
>>> 
>>> 
>>> for person in data:
...     print person['firstName'] + ' ' + person['lastName']
... 
John Doe
Anna Smith
Angel Cool
>>> 
>>> data.reverse()
>>> 
>>> for person in data:
...     print person['firstName'] + ' ' + person['lastName']
... 
Angel Cool
Anna Smith
John Doe
>>>

>>> print 'Donald Trump'[::-1]
