+r"""JSON (JavaScript Object Notation) <https://json.org> is a subset of

+interchange format.
+
+:mod:`json` exposes an API familiar to users of the standard library
+:mod:`marshal` and :mod:`pickle` modules.  It is derived from a
+version of the externally maintained simplejson library.
+
+Encoding basic Python object hierarchies::
+
+    >>> import 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('\u1234'))

+    >>> from io import StringIO
+    >>> io = StringIO()
+    >>> json.dump(['streaming API'], io)
+    >>> io.getvalue()
+    '["streaming API"]'
+
+Compact encoding::
+
+    >>> import json
+    >>> mydict = {'4': 5, '6': 7}
+    >>> json.dumps([1,2,3,mydict], separators=(',', ':'))
+    '[1,2,3,{"4":5,"6":7}]'
+
+Pretty printing::
+
+    >>> import json

+    {
+        "4": 5,
+        "6": 7
+    }
+
+Decoding JSON::
+
+    >>> import json
+    >>> obj = ['foo', {'bar': ['baz', None, 1.0, 2]}]
+    >>> json.loads('["foo", {"bar":["baz", null, 1.0, 2]}]') == obj
+    True

+    True
+    >>> from io import StringIO
+    >>> io = StringIO('["streaming API"]')
+    >>> json.load(io)[0] == 'streaming API'
+    True
+
+Specializing JSON object decoding::
+
+    >>> import json
+    >>> def as_complex(dct):
+    ...     if '__complex__' in dct:
+    ...         return complex(dct['real'], dct['imag'])
+    ...     return dct

+    (1+2j)
+    >>> from decimal import Decimal
+    >>> json.loads('1.1', parse_float=Decimal) == Decimal('1.1')
+    True
+
+Specializing JSON object encoding::
+
+    >>> import json
+    >>> def encode_complex(obj):
+    ...     if isinstance(obj, complex):
+    ...         return [obj.real, obj.imag]
+    ...     raise TypeError(f'Object of type {obj.__class__.__name__} '
+    ...                     f'is not JSON serializable')

+        encoding of keys that are not str, int, float or None.  If
+        skipkeys is True, such items are simply skipped.
+
+        If ensure_ascii is true, the output is guaranteed to be str
+        objects with all incoming non-ASCII characters escaped.  If
+        ensure_ascii is false, the output can contain non-ASCII characters.
+
+        If check_circular is true, then lists, dicts, and custom encoded
+        objects will be checked for circular references during encoding to
+        prevent an infinite recursion (which would cause an RecursionError).
+        Otherwise, no such check takes place.

+        but is consistent with most JavaScript based encoders and decoders.
+        Otherwise, it will be a ValueError to encode such floats.
+
+        If sort_keys is true, then the output of dictionaries will be
+        sorted by key; this is useful for regression tests to ensure
+        that JSON serializations can be compared on a day-to-day basis.
+
+        If indent is a non-negative integer, then JSON array
+        elements and object members will be pretty-printed with that
+        indent level.  An indent level of 0 will only insert newlines.
