Contents
=============
* ``frozendict``: An immutable dictionary that cannot be changed after creation.
* ``FrozenOrderedDict``: An immutable ``OrderedDict`` where the order of keys is preserved, but that cannot be changed after creation.
* ``AlphaDict``: A ``FrozenOrderedDict`` where the keys are stored in alphabetical order.
* ``bdict``: A dictionary where ``key, value`` pairs are stored both ways round.
This package also provides two base classes for creating your own custom dictionaries:
* ``FrozenBase``: An Abstract Base Class for Frozen dictionaries.
* ``MutableBase``: An Abstract Base Class for mutable dictionaries.
|
Other Dictionary Packages
===========================
If you're looking to unflatten a dictionary, such as to go from this:
.. code-block:: python
{"foo.bar": "val"}
to this:
.. code-block:: python
{"foo": {"bar": "val"}}
check out `unflatten`_, `flattery`_ or `morph`_ to accomplish that.
.. _unflatten: https://github.com/dairiki/unflatten
.. _morph: https://github.com/metagriffin/morph
.. _flattery: https://github.com/acg/python-flattery
`indexed`_ provides an OrderedDict where the values can be accessed by their index as well as by their keys.
.. _indexed: https://github.com/niklasf/indexed.py
There's also `python-benedict`_, which provides a custom dictionary with **keylist/keypath** support, **I/O** shortcuts (``Base64``, ``CSV``, ``JSON``, ``TOML``, ``XML``, ``YAML``, ``pickle``, ``query-string``) and many **utilities**.
.. _python-benedict: https://github.com/fabiocaccamo/python-benedict
Installation
===========================
.. start installation
``Cawdrey`` can be installed from PyPI or Anaconda.
To install with ``pip``:
.. code-block:: bash
$ python -m pip install cawdrey
To install with ``conda``:
* First add the required channels
.. code-block:: bash
$ conda config --add channels https://conda.anaconda.org/conda-forge
$ conda config --add channels https://conda.anaconda.org/domdfcoding
* Then install
.. code-block:: bash
$ conda install cawdrey
.. end installation
And Finally:
