PyObject *`_PyObject_New`(PyTypeObject *type)
  반환값: 새 참조.

PyVarObject *`_PyObject_NewVar`(PyTypeObject *type, Py_ssize_t size)
  반환값: 새 참조.

PyObject *`PyObject_Init`(PyObject *op, PyTypeObject *type)
  반환값: 빌린 참조. Part of the Stable ABI.

  Initialize a newly allocated object op with its type and initial reference. Returns the initialized object. If type indicates that the object participates in the cyclic garbage detector, it is added to the detector’s set of observed objects. Other fields of the object are not affected.

PyVarObject *`PyObject_InitVar`(PyVarObject *op, PyTypeObject *type, Py_ssize_t size)
  반환값: 빌린 참조. Part of the Stable ABI.

  이것은 `PyObject_Init()`가 수행하는 모든 작업을 수행하고, 가변 크기 객체의 길이 정보도 초기화합니다.

TYPE *`PyObject_New`(TYPE, PyTypeObject *type)
  반환값: 새 참조.

  Allocate a new Python object using the C structure type TYPE and the Python type object type. Fields not defined by the Python object header are not initialized. The caller will own the only reference to the object (i.e. its reference count will be one). The size of the memory allocation is determined from the `tp_basicsize` field of the type object.

TYPE *`PyObject_NewVar`(TYPE, PyTypeObject *type, Py_ssize_t size)
  반환값: 새 참조.

  Allocate a new Python object using the C structure type TYPE and the Python type object type. Fields not defined by the Python object header are not initialized. The allocated memory allows for the TYPE structure plus size fields of the size given by the `tp_itemsize` field of type. This is useful for implementing objects like tuples, which are able to determine their size at construction time. Embedding the array of fields into the same allocation decreases the number of allocations, improving the memory management efficiency.

void `PyObject_Del`(void *op)

  Releases memory allocated to an object using `PyObject_New()` or `PyObject_NewVar()`. This is normally called from the `tp_dealloc` handler specified in the object’s type. The fields of the object should not be accessed after this call as the memory is no longer a valid Python object.

PyObject `_Py_NoneStruct`

  파이썬에서 `None`으로 노출되는 객체. 이 객체에 대한 포인터로 평가되는 `Py_None` 매크로를 사용해서 액세스해야 합니다.
