'''
The ``domains`` module provides functions for creating and using domains.
For more context, see :ref:`domains in the User Guide <domains-user-guide>`.
For convenience, all the functions of this module are also available from :py:mod:`opendp.prelude`.
We suggest importing under the conventional name ``dp``:
.. code:: python
>>> import opendp.prelude as dp
