:mod:`types` --- Names for built-in types
|

|
:synopsis: Names for built-in types.
|
|
|
|
**Source code:** :source:`Lib/types.py`
|
|
|
|
--------------
|
|
|
|
This module defines names for some object types that are used by the standard
|
|
Python interpreter, but not exposed as builtins like :class:`int` or
|
|
:class:`str` are. Also, it does not include some of the types that arise
|
|
transparently during processing such as the ``listiterator`` type.
|
|
|
|
Typical use is for :func:`isinstance` or :func:`issubclass` checks.
|
|
|
|
The module defines the following names:
|
|
|
|
.. data:: FunctionType
|
|
LambdaType
|
|
|
|
The type of user-defined functions and functions created by :keyword:`lambda`
|
|
expressions.
|
|
|
|
|
|
.. data:: GeneratorType
|
|
|
|
The type of :term:`generator`-iterator objects, produced by calling a
|
|
generator function.
|
|
|
|
|
|
.. data:: CodeType
|
|
|
|
.. index:: builtin: compile
|
|
|
|
The type for code objects such as returned by :func:`compile`.
|
|
|
|
|
|
.. data:: MethodType
|
|
|
|
The type of methods of user-defined class instances.
|
|
|
|
|
|
.. data:: BuiltinFunctionType
|
|
BuiltinMethodType
|
|
|
|
The type of built-in functions like :func:`len` or :func:`sys.exit`, and
|
|
methods of built-in classes. (Here, the term "built-in" means "written in
|
|
C".)
|
|
|
|
|
|
.. data:: ModuleType
|
|
|
|
The type of modules.
|
|
|
|
|
|
.. data:: TracebackType
|
|
|
|
The type of traceback objects such as found in ``sys.exc_info()[2]``.
|
|
|
|
|
|
.. data:: FrameType
|
|
|
|
The type of frame objects such as found in ``tb.tb_frame`` if ``tb`` is a
|
|
traceback object.
|
|
|
|
|
|
.. data:: GetSetDescriptorType
|
|
|
|
The type of objects defined in extension modules with ``PyGetSetDef``, such
|
|
as ``FrameType.f_locals`` or ``array.array.typecode``. This type is used as
|
|
descriptor for object attributes; it has the same purpose as the
|
|
:class:`property` type, but for classes defined in extension modules.
|
|
|
|
|
|
.. data:: MemberDescriptorType
|
|
|
|
The type of objects defined in extension modules with ``PyMemberDef``, such
|
|
as ``datetime.timedelta.days``. This type is used as descriptor for simple C
|
|
data members which use standard conversion functions; it has the same purpose
|
|
as the :class:`property` type, but for classes defined in extension modules.
|
|
|
|
.. impl-detail::
|
|
|
|
In other implementations of Python, this type may be identical to
|
|
``GetSetDescriptorType``.
