API Reference

This page gives an overview of all public pandas objects, functions and
methods. All classes and functions exposed in ``pandas.*`` namespace are public.

Some subpackages are public which include ``pandas.errors``,
``pandas.plotting``, and ``pandas.testing``. Public functions in
``pandas.io`` and ``pandas.tseries`` submodules are mentioned in
the documentation. ``pandas.api.types`` subpackage holds some
public functions related to data types in pandas.


.. warning::

    The ``pandas.core``, ``pandas.compat``, and ``pandas.util`` top-level modules are PRIVATE. Stable functionality in such modules is not guaranteed.

..
    The following is needed to ensure the generated pages are created with the
    correct template (otherwise they would be created in the Series/Index class page)

..
    .. autosummary::
       :toctree: generated/
       :template: autosummary/accessor.rst

       Series.str
       Series.cat
       Series.dt
       Index.str

.. _api.categorical:

Categorical
~~~~~~~~~~~

Pandas defines a custom data type for representing data that can take only a
limited, fixed set of values. The dtype of a ``Categorical`` can be described by
a :class:`pandas.api.types.CategoricalDtype`.

.. autosummary::
   :toctree: generated/
   :template: autosummary/class_without_autosummary.rst

   api.types.CategoricalDtype

.. autosummary::
   :toctree: generated/

   api.types.CategoricalDtype.categories
   api.types.CategoricalDtype.ordered

Categorical data can be stored in a :class:`pandas.Categorical`

.. autosummary::
   :toctree: generated/
   :template: autosummary/class_without_autosummary.rst

   Categorical


The alternative :meth:`Categorical.from_codes` constructor can be used when you
have the categories and integer codes already:

.. autosummary::
   :toctree: generated/

   Categorical.from_codes

The dtype information is available on the ``Categorical``

.. autosummary::
   :toctree: generated/

   Categorical.dtype
   Categorical.categories
   Categorical.ordered
   Categorical.codes

``np.asarray(categorical)`` works by implementing the array interface. Be aware, that this converts
the Categorical back to a NumPy array, so categories and order information is not preserved!

.. autosummary::
   :toctree: generated/

   Categorical.__array__

A ``Categorical`` can be stored in a ``Series`` or ``DataFrame``.
To create a Series of dtype ``category``, use ``cat = s.astype(dtype)`` or
``Series(..., dtype=dtype)`` where ``dtype`` is either

* the string ``'category'``
* an instance of :class:`~pandas.api.types.CategoricalDtype`.

If the Series is of dtype ``CategoricalDtype``, ``Series.cat`` can be used to change the categorical
data. This accessor is similar to the ``Series.dt`` or ``Series.str`` and has the
following usable methods and properties:

.. autosummary::
   :toctree: generated/
   :template: autosummary/accessor_attribute.rst

   Series.cat.categories
   Series.cat.ordered
   Series.cat.codes

.. autosummary::
   :toctree: generated/
   :template: autosummary/accessor_method.rst

   Series.cat.rename_categories
   Series.cat.reorder_categories
   Series.cat.add_categories
   Series.cat.remove_categories
   Series.cat.remove_unused_categories
   Series.cat.set_categories
   Series.cat.as_ordered
   Series.cat.as_unordered

Plotting
~~~~~~~~

``Series.plot`` is both a callable method and a namespace attribute for
specific plotting methods of the form ``Series.plot.<kind>``.

.. autosummary::
   :toctree: generated/
