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

| .. module:: types |
| :synopsis: Names for built-in types. |
| |
| |
| 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``. |
