# `json` – JSON encoding and decoding

This module implements a subset of the corresponding CPython module, as described below. For more information, refer to the original CPython documentation: `json`.

This modules allows to convert between Python objects and the JSON data format.

## Functions

json.dump(obj, stream, separators=None)

  Serialise obj to a JSON string, writing it to the given stream.

  If specified, separators should be an `(item_separator, key_separator)` tuple. The default is `(', ', ': ')`. To get the most compact JSON representation, you should specify `(',', ':')` to eliminate whitespace.

json.dumps(obj, separators=None)

  Return obj represented as a JSON string.

  The arguments have the same meaning as in `dump`.

json.load(stream)

  Parse the given stream, interpreting it as a JSON string and deserialising the data to a Python object. The resulting object is returned.

  Parsing continues until end-of-file is encountered. A `ValueError` is raised if the data in stream is not correctly formed.

json.loads(str)

  Parse the JSON str and return an object. Raises `ValueError` if the string is not correctly formed.
