Signature : json.loads(s, encoding=None, cls=None, object_hook=None, parse_float=None, parse_int=None, parse_constant=None, object_pairs_hook=None, **kwds)
Docstring :
Deserialize "s" (a "str" or "unicode" instance containing a JSON
document) to a Python object.

If "s" is a "str" instance and is encoded with an ASCII based
encoding other than utf-8 (e.g. latin-1) then an appropriate
"encoding" name must be specified. Encodings that are not ASCII
based (such as UCS-2) are not allowed and should be decoded to
"unicode" first.

"object_hook" is an optional function that will be called with the
result of any object literal decode (a "dict"). The return value of
"object_hook" will be used instead of the "dict". This feature can
be used to implement custom decoders (e.g. JSON-RPC class hinting).

"object_pairs_hook" is an optional function that will be called
with the result of any object literal decoded with an ordered list
of pairs.  The return value of "object_pairs_hook" will be used
instead of the "dict". This feature can be used to implement custom
decoders that rely on the order that the key and value pairs are
decoded (for example, collections.OrderedDict will remember the
order of insertion). If "object_hook" is also defined, the
"object_pairs_hook" takes priority.

"parse_float", if specified, will be called with the string of
every JSON float to be decoded. By default this is equivalent to
float(num_str). This can be used to use another datatype or parser
for JSON floats (e.g. decimal.Decimal).

"parse_int", if specified, will be called with the string of every
JSON int to be decoded. By default this is equivalent to
int(num_str). This can be used to use another datatype or parser
for JSON integers (e.g. float).

"parse_constant", if specified, will be called with one of the
following strings: -Infinity, Infinity, NaN, null, true, false.
This can be used to raise an exception if invalid JSON numbers are
encountered.

To use a custom "JSONDecoder" subclass, specify it with the "cls"
kwarg; otherwise "JSONDecoder" is used.
