-

-        The return value of *object_pairs_hook* will be used instead of the

-        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. :class:`decimal.Decimal`).
-

-        can be used to raise an exception if invalid JSON numbers are
-        encountered.

-        *strict* controls the parser's behavior when it encounters an
-        invalid control character in a string. The default setting of
