The C structure of the objects used to describe built-in types.
This is the type object for type objects; it is the same object as type and types.TypeType 在 Python 层。
Return true if the object o is a type object, including instances of types derived from the standard type object. Return false in all other cases.
Return true if the object o is a type object, but not a subtype of the standard type object. Return false in all other cases.
2.2 版新增。
Clear the internal lookup cache. Return the current version tag.
2.6 版新增。
Invalidate the internal lookup cache for the type and all of its subtypes. This function must be called after any manual modification of the attributes or base classes of the type.
2.6 版新增。
Return true if the type object o sets the feature feature . Type features are denoted by single bit flags.
Return true if the type object includes support for the cycle detector; this tests the type flag Py_TPFLAGS_HAVE_GC .
2.0 版新增。
返回 True 若 a is a subtype of b .
2.2 版新增。
This function only checks for actual subtypes, which means that __subclasscheck__() is not called on b 。调用 PyObject_IsSubclass() to do the same check that issubclass() would do.
2.2 版新增。
Changed in version 2.5: This function used an int type for nitems . This might require changes in your code for properly supporting 64-bit systems.
2.2 版新增。
Finalize a type object. This should be called on all type objects to finish their initialization. This function is responsible for adding inherited slots from a type’s base class. Return 0 on success, or return -1 and sets an exception on error.
