.. class:: Container
Hashable
Sized
Callable
ABCs for classes that provide respectively the methods :meth:`__contains__`,
:meth:`__hash__`, :meth:`__len__`, and :meth:`__call__`.
.. class:: Iterable
ABC for classes that provide the :meth:`__iter__` method.
See also the definition of :term:`iterable`.
.. class:: Iterator
ABC for classes that provide the :meth:`__iter__` and :meth:`next` methods.
See also the definition of :term:`iterator`.
.. class:: Sequence
MutableSequence
ABCs for read-only and mutable :term:`sequences <sequence>`.
.. class:: Set
MutableSet
ABCs for read-only and mutable sets.
.. class:: Mapping
MutableMapping
ABCs for read-only and mutable :term:`mappings <mapping>`.
.. class:: MappingView
ItemsView
KeysView
ValuesView
ABCs for mapping, items, keys, and values :term:`views <view>`.
These ABCs allow us to ask classes or instances if they provide
particular functionality, for example::
