It is the externally maintained version of the :mod:`json` library contained in Python 2.6, but maintains compatibility back to Python 2.5 and (currently) has significant performance advantages, even without using the optional C extension for speedups. Encoding basic Python object hierarchies:: >>> import simplejson as json >>> json.dumps(['foo', {'bar': ('baz', None, 1.0, 2)}]) '["foo", {"bar": ["baz", null, 1.0, 2]}]' >>> print(json.dumps("\"foo\bar")) "\"foo\bar" >>> print(json.dumps(u'\u1234')) "\u1234" >>> print(json.dumps('\\')) "\\" >>> print(json.dumps({"c": 0, "b": 0, "a": 0}, sort_keys=True)) {"a": 0, "b": 0, "c": 0} >>> from simplejson.compat import StringIO >>> io = StringIO() >>> json.dump(['streaming API'], io) >>> io.getvalue() '["streaming API"]' Compact encoding:: >>> import simplejson as json >>> obj = [1,2,3,{'4': 5, '6': 7}] >>> json.dumps(obj, separators=(',',':'), sort_keys=True) '[1,2,3,{"4":5,"6":7}]' Pretty printing:: >>> import simplejson as json >>> print(json.dumps({'4': 5, '6': 7}, sort_keys=True, indent=' ')) { "4": 5, "6": 7 } Decoding JSON:: >>> import simplejson as json >>> obj = [u'foo', {u'bar': [u'baz', None, 1.0, 2]}] >>> json.loads('["foo", {"bar":["baz", null, 1.0, 2]}]') == obj True >>> json.loads('"\\"foo\\bar"') == u'"foo\x08ar' True >>> from simplejson.compat import StringIO >>> io = StringIO('["streaming API"]') >>> json.load(io)[0] == 'streaming API' True Specializing JSON object decoding:: >>> import simplejson as json >>> def as_complex(dct): ... if '__complex__' in dct: ... return complex(dct['real'], dct['imag']) ... return dct ... >>> json.loads('{"__complex__": true, "real": 1, "imag": 2}', ... object_hook=as_complex) (1+2j) >>> from decimal import Decimal >>> json.loads('1.1', parse_float=Decimal) == Decimal('1.1') True Specializing JSON object encoding:: >>> import simplejson as json >>> def encode_complex(obj): ... if isinstance(obj, complex): ... return [obj.real, obj.imag] ... raise TypeError(repr(o) + " is not JSON serializable") ... >>> json.dumps(2 + 1j, default=encode_complex) '[2.0, 1.0]' >>> json.JSONEncoder(default=encode_complex).encode(2 + 1j) '[2.0, 1.0]' >>> ''.join(json.JSONEncoder(default=encode_complex).iterencode(2 + 1j)) '[2.0, 1.0]' Using simplejson.tool from the shell to validate and pretty-print:: $ echo '{"json":"obj"}' | python -m simplejson.tool { "json": "obj" } $ echo '{ 1.2:3.4}' | python -m simplejson.tool Expecting property name: line 1 column 3 (char 2) � )�absolute_importz3.12.0�dump�dumps�load�loads� JSONDecoder�JSONDecodeError� JSONEncoder� OrderedDict� simple_first�RawJSONz Bob Ippolito <bob@redivi.com>)�Decimal� )r )r )r )r �JSONEncoderForHTMLc C s6 dd l } y| jS tk r0 ddlm} |jS X d S )Nr r )� ordered_dict)� collectionsr �AttributeError� r )r r � r �F/opt/alt/python37/lib64/python3.7/site-packages/simplejson/__init__.py�_import_OrderedDicts s r c C s* yddl m} | S tk r$ d S X d S )Nr )� make_encoder)Z _speedupsr � ImportError)r r r r �_import_c_make_encoder| s r FTN�utf-8)�skipkeys� ensure_ascii�check_circular� allow_nan�indent� separators�encoding�default� use_decimal�namedtuple_as_object�tuple_as_array�iterable_as_array�bigint_as_string� item_sort_key�for_json� ignore_nan�int_as_string_bitcountc K s� |st|rt|rt|rt|dkrt|dkrt|dkrt| dkrt| dkrt| rt| rt| rt|st|st|st|st|st|st|dkrt|stt �| �}nF|dkr�t}|f ||||||| | | | | |||||||d�|���| �}x|D ]}|�|� q�W dS )ak Serialize ``obj`` as a JSON formatted stream to ``fp`` (a ``.write()``-supporting file-like object). If *skipkeys* is true then ``dict`` keys that are not basic types (``str``, ``unicode``, ``int``, ``long``, ``float``, ``bool``, ``None``) will be skipped instead of raising a ``TypeError``. If *ensure_ascii* is false, then the some chunks written to ``fp`` may be ``unicode`` instances, subject to normal Python ``str`` to ``unicode`` coercion rules. Unless ``fp.write()`` explicitly understands ``unicode`` (as in ``codecs.getwriter()``) this is likely to cause an error. If *check_circular* is false, then the circular reference check for container types will be skipped and a circular reference will result in an ``OverflowError`` (or worse). If *allow_nan* is false, then it will be a ``ValueError`` to serialize out of range ``float`` values (``nan``, ``inf``, ``-inf``) in strict compliance of the original JSON specification, instead of using the JavaScript equivalents (``NaN``, ``Infinity``, ``-Infinity``). See *ignore_nan* for ECMA-262 compliant behavior. If *indent* is a string, then JSON array elements and object members will be pretty-printed with a newline followed by that string repeated for each level of nesting. ``None`` (the default) selects the most compact representation without any newlines. For backwards compatibility with versions of simplejson earlier than 2.1.0, an integer is also accepted and is converted to a string with that many spaces. If specified, *separators* should be an ``(item_separator, key_separator)`` tuple. The default is ``(', ', ': ')`` if *indent* is ``None`` and ``(',', ': ')`` otherwise. To get the most compact JSON representation, you should specify ``(',', ':')`` to eliminate whitespace. *encoding* is the character encoding for str instances, default is UTF-8. *default(obj)* is a function that should return a serializable version of obj or raise ``TypeError``. The default simply raises ``TypeError``. If *use_decimal* is true (default: ``True``) then decimal.Decimal will be natively serialized to JSON with full precision. If *namedtuple_as_object* is true (default: ``True``), :class:`tuple` subclasses with ``_asdict()`` methods will be encoded as JSON objects. If *tuple_as_array* is true (default: ``True``), :class:`tuple` (and subclasses) will be encoded as JSON arrays. If *iterable_as_array* is true (default: ``False``), any object not in the above table that implements ``__iter__()`` will be encoded as a JSON array. If *bigint_as_string* is true (default: ``False``), ints 2**53 and higher or lower than -2**53 will be encoded as strings. This is to avoid the rounding that happens in Javascript otherwise. Note that this is still a lossy operation that will not round-trip correctly and should be used sparingly. If *int_as_string_bitcount* is a positive number (n), then int of size greater than or equal to 2**n or lower than or equal to -2**n will be encoded as strings. If specified, *item_sort_key* is a callable used to sort the items in each dictionary. This is useful if you want to sort items other than in alphabetical order by key. This option takes precedence over *sort_keys*. If *sort_keys* is true (default: ``False``), the output of dictionaries will be sorted by item. If *for_json* is true (default: ``False``), objects with a ``for_json()`` method will use the return value of that method for encoding as JSON instead of the object. If *ignore_nan* is true (default: ``False``), then out of range :class:`float` values (``nan``, ``inf``, ``-inf``) will be serialized as ``null`` in compliance with the ECMA-262 specification. If true, this will override *allow_nan*. To use a custom ``JSONEncoder`` subclass (e.g. one that overrides the ``.default()`` method to serialize additional types), specify it with the ``cls`` kwarg. NOTE: You should use *default* or *for_json* instead of subclassing whenever possible.
