PyObject *_PyObject_New(PyTypeObject *type)
  Valeur de retour : nouvelle référence.

PyVarObject *_PyObject_NewVar(PyTypeObject *type, Py_ssize_t size)
  Valeur de retour : nouvelle référence.

PyObject *PyObject_Init(PyObject *op, PyTypeObject *type)
  Valeur de retour : référence empruntée. 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)
  Valeur de retour : référence empruntée. Part of the Stable ABI.

  Effectue les mêmes opérations que `PyObject_Init()` fait, et initialise également l'information de la longueur pour un objet de taille variable.

PyObject_New(TYPE, typeobj)

  Allocate a new Python object using the C structure type TYPE and the Python type object typeobj (`PyTypeObject*`). 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.

PyObject_NewVar(TYPE, typeobj, size)

  Allocate a new Python object using the C structure type TYPE and the Python type object typeobj (`PyTypeObject*`). Fields not defined by the Python object header are not initialized. The allocated memory allows for the TYPE structure plus size (`Py_ssize_t`) fields of the size given by the `tp_itemsize` field of typeobj. 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

  Objet qui est visible en tant que `None` dans Python. Ne devrait être accessible uniquement en utilisant la macro `Py_None`, qui évalue cet objet à un pointeur.
