__name__ = '<doctest>'
This module implements high-performance container datatypes. Currently,
there are two datatypes, :class:`deque` and :class:`defaultdict`, and
one datatype factory function, :func:`namedtuple`.
.. versionchanged:: 2.5
Added :class:`defaultdict`.
.. versionchanged:: 2.6
Added :func:`namedtuple`.
there are three datatypes, :class:`Counter`, :class:`deque` and
:class:`defaultdict`, and one datatype factory function, :func:`namedtuple`.
The specialized containers provided in this module provide alternatives
to Python's general purpose built-in containers, :class:`dict`,
:class:`list`, :class:`set`, and :class:`tuple`.
Besides the containers provided here, the optional :mod:`bsddb`
module offers the ability to create in-memory or file based ordered
dictionaries with string keys using the :meth:`bsddb.btopen` method.
.. versionchanged:: 2.4
Added :class:`deque`.
.. versionchanged:: 2.5
Added :class:`defaultdict`.
.. versionchanged:: 2.6
Added :func:`namedtuple` and added abstract base classes.
.. versionchanged:: 2.7
Added :class:`Counter`.
In addition to containers, the collections module provides some ABCs
(abstract base classes) that can be used to test whether a class
provides a particular interface, for example, is it hashable or
provides a particular interface, for example, whether it is hashable or
a mapping.
.. versionchanged:: 2.6
Added abstract base classes.
