7.10. types
— Names for built-in types¶
Source code: 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 int
or
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 isinstance()
or issubclass()
checks.
The module defines the following names:
-
types.
FunctionType
¶ -
types.
LambdaType
¶ The type of user-defined functions and functions created by
lambda
expressions.
-
types.
GeneratorType
¶ The type of generator-iterator objects, produced by calling a generator function.
-
types.
MethodType
¶ The type of methods of user-defined class instances.
-
types.
BuiltinFunctionType
¶ -
types.
BuiltinMethodType
¶ The type of built-in functions like
len()
orsys.exit()
, and methods of built-in classes. (Here, the term “built-in” means “written in C”.)
-
types.
ModuleType
¶ The type of modules.
-
types.
TracebackType
¶ The type of traceback objects such as found in
sys.exc_info()[2]
.
-
types.
FrameType
¶ The type of frame objects such as found in
tb.tb_frame
iftb
is a traceback object.
-
types.
GetSetDescriptorType
¶ The type of objects defined in extension modules with
PyGetSetDef
, such asFrameType.f_locals
orarray.array.typecode
. This type is used as descriptor for object attributes; it has the same purpose as theproperty
type, but for classes defined in extension modules.
-
types.
MemberDescriptorType
¶ The type of objects defined in extension modules with
PyMemberDef
, such asdatetime.timedelta.days
. This type is used as descriptor for simple C data members which use standard conversion functions; it has the same purpose as theproperty
type, but for classes defined in extension modules.CPython implementation detail: In other implementations of Python, this type may be identical to
GetSetDescriptorType
.
