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.  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.

   Note that this function is unsuitable if *typeobj* has
   "Py_TPFLAGS_HAVE_GC" set. For such objects, use "PyObject_GC_New()"
   instead.

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.

   Note that this function is unsuitable if *typeobj* has
   "Py_TPFLAGS_HAVE_GC" set. For such objects, use
   "PyObject_GC_NewVar()" instead.

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.
