Purpose
-------
This library provides a function for partitioning `iterable <https://docs.python.org/3/glossary.html#term-iterable>`__ data structure instances. When the number of parts is specified explicitly, it is treated as a strict requirement and an exception is raised when it cannot be satisfied. When a length for all parts (or each part) is specified explicitly, a best-effort approach is used: as many parts of the specified length are retrieved as possible, with the possibility that some parts at the end of the partition sequence have a shorter (but still non-zero) length.
Installation and Usage
----------------------
This library is available as a `package on PyPI <https://pypi.org/project/parts>`__:
.. code-block:: bash
python -m pip install parts
The library can be imported in the usual manner:
.. code-block:: python
import parts
from parts import parts
Examples
^^^^^^^^
Several examples are presented below:
.. code-block:: python
>>> list(parts([1, 2, 3, 4, 5, 6, 7], length=2))
[[1, 2], [3, 4], [5, 6], [7]]
>>> list(parts([1, 2, 3, 4, 5, 6, 7], length=4))
[[1, 2, 3, 4], [5, 6, 7]]
>>> list(parts([1, 2, 3, 4, 5, 6, 7], number=1))
[[1, 2, 3, 4, 5, 6, 7]]
>>> list(parts([1, 2, 3, 4, 5, 6, 7], 5))
[[1], [2], [3], [4, 5], [6, 7]]
>>> list(parts([1, 2, 3, 4, 5, 6], 2, 3))
[[1, 2, 3], [4, 5, 6]]
>>> list(parts([1, 2, 3, 4, 5, 6], number=3, length=2))
[[1, 2], [3, 4], [5, 6]]
>>> list(parts([1, 2, 3, 4, 5, 6, 7], 7, [1, 1, 1, 1, 1, 1, 1]))
[[1], [2], [3], [4], [5], [6], [7]]
>>> list(parts([1, 2, 3, 4, 5, 6], length=[2, 2, 2]))
[[1, 2], [3, 4], [5, 6]]
>>> list(parts([1, 2, 3, 4, 5, 6], length=[1, 2, 3]))
[[1], [2, 3], [4, 5, 6]]
>>> list(parts([1, 2, 3, 4, 5, 6, 7], number=3, length=2))
Traceback (most recent call last):
...
ValueError: cannot retrieve 3 parts from object given part length parameter of 2
Development
-----------
All installation and development dependencies are fully specified in ``pyproject.toml``. The ``project.optional-dependencies`` object is used to `specify optional requirements <https://peps.python.org/pep-0621>`__ for various development tasks. This makes it possible to specify additional options (such as ``docs``, ``lint``, and so on) when performing installation using `pip <https://pypi.org/project/pip>`__:
.. code-block:: bash
python -m pip install ".[docs,lint]"
Documentation
^^^^^^^^^^^^^
The documentation can be generated automatically from the source files using `Sphinx <https://www.sphinx-doc.org>`__:
.. code-block:: bash
python -m pip install ".[docs]"
cd docs
sphinx-apidoc -f -E --templatedir=_templates -o _source .. && make html
Testing and Conventions
^^^^^^^^^^^^^^^^^^^^^^^
All unit tests are executed and their coverage is measured when using `pytest <https://docs.pytest.org>`__ (see the ``pyproject.toml`` file for configuration details):
.. code-block:: bash
python -m pip install ".[test]"
python -m pytest
Alternatively, all unit tests are included in the module itself and can be executed using `doctest <https://docs.python.org/3/library/doctest.html>`__:
.. code-block:: bash
python src/parts/parts.py -v
Style conventions are enforced using `Pylint <https://pylint.readthedocs.io>`__:
.. code-block:: bash
python -m pip install ".[lint]"
python -m pylint src/parts
Contributions
^^^^^^^^^^^^^
In order to contribute to the source code, open an issue or submit a pull request on the `GitHub page <https://github.com/lapets/parts>`__ for this library.
Versioning
^^^^^^^^^^
Beginning with version 0.2.0, the version number format for this library and the changes to the library associated with version number increments conform with `Semantic Versioning 2.0.0 <https://semver.org/#semantic-versioning-200>`__.
Publishing
^^^^^^^^^^
This library can be published as a `package on PyPI <https://pypi.org/project/parts>`__ via the GitHub Actions workflow found in ``.github/workflows/build-publish-sign-release.yml`` that follows the `recommendations found in the Python Packaging User Guide <https://packaging.python.org/en/latest/guides/publishing-package-distribution-releases-using-github-actions-ci-cd-workflows/>`__.
Ensure that the correct version number appears in ``pyproject.toml``, and that any links in this README document to the Read the Docs documentation of this package (or its dependencies) have appropriate version numbers. Also ensure that the Read the Docs project for this library has an `automation rule <https://docs.readthedocs.io/en/stable/automation-rules.html>`__ that activates and sets as the default all tagged versions.
To publish the package, create and push a tag for the version being published (replacing ``?.?.?`` with the version number):
.. code-block:: bash
git tag ?.?.?
git push origin ?.?.?
