>>> from jsondiff import diff

>>> diff({'a': 1}, {'a': 1, 'b': 2})
{<insert>: {'b': 2}}

>>> diff({'a': 1, 'b': 3}, {'a': 1, 'b': 2})
{<update>: {'b': 2}}

>>> diff({'a': 1, 'b': 3}, {'a': 1})
{<delete>: ['b']}

>>> diff(['a', 'b', 'c'], ['a', 'b', 'c', 'd'])
{<insert>: [(3, 'd')]}

>>> diff(['a', 'b', 'c'], ['a', 'c'])
{<delete>: [1]}

# Similar items get patched
>>> diff(['a', {'x': 3}, 'c'], ['a', {'x': 3, 'y': 4}, 'c'])
{<update>: [(1, {<insert>: {'y': 4}})]}

# Special handling of sets
>>> diff({'a', 'b', 'c'}, {'a', 'c', 'd'})
{<add>: set(['d']), <discard>: set(['b'])}

# Parse and dump JSON
>>> print diff('["a", "b", "c"]', '["a", "c", "d"]', parse=True, dump=True, indent=2)
