.. versionadded:: 2.4
This module implements high-performance container datatypes. Currently, there
are two datatypes, deque and defaultdict, and one datatype factory function,
:func:`NamedTuple`. Future additions may include balanced trees and ordered
dictionaries.
This module implements high-performance container datatypes. Currently,
there are two datatypes, :class:`deque` and :class:`defaultdict`, and
one datatype factory function, :func:`NamedTuple`. Python already
includes built-in containers, :func:`dict`, :func:`list`, and
:func:`tuple`. The optional :mod:`bsddb` module has a :meth:`btopen`
method that can be used to create in-memory or file based ordered
dictionaries with string keys.
Future editions of the standard library may include balanced trees and
ordered dictionaries.
