# Itérateurs

Python provides two general-purpose iterator objects. The first, a sequence iterator, works with an arbitrary sequence supporting the `__getitem__()` method. The second works with a callable object and a sentinel value, calling the callable for each item in the sequence, and ending the iteration when the sentinel value is returned.

PyTypeObject PySeqIter_Type
  Part of the Stable ABI.

  Type des itérateurs renvoyés par les fonctions `PySeqIter_New()` et la forme à un argument de la fonction native `iter()` pour les séquences natives.

int PySeqIter_Check( PyObject *op)

  Return true if the type of op is `PySeqIter_Type`. This function always succeeds.

PyObject *PySeqIter_New( PyObject *seq)
  Valeur de retour : nouvelle référence. Part of the Stable ABI.

  Renvoie un itérateur sur la séquence seq. L'itération prend fin lorsque la séquence lève `IndexError` lors d'une tentative d'accès.

PyTypeObject PyCallIter_Type
  Part of the Stable ABI.

  Type de l'itérateur renvoyé par les fonctions `PyCallIter_New()` et `iter()` à deux arguments.

int PyCallIter_Check( PyObject *op)

  Return true if the type of op is `PyCallIter_Type`. This function always succeeds.

PyObject *PyCallIter_New( PyObject *callable, PyObject *sentinel)
  Valeur de retour : nouvelle référence. Part of the Stable ABI.

  Renvoie un nouvel itérateur. Le premier paramètre, callable, peut être n'importe quel objet Python appelable sans aucun paramètre ; chaque appel doit renvoyer l'élément suivant de l'itération. Lorsque callable renvoie une valeur égale à sentinel, l'itération prend fin.

## Range Objects

PyTypeObject PyRange_Type
  Part of the Stable ABI.

  The type object for `range` objects.

int PyRange_Check( PyObject *o)

  Return true if the object o is an instance of a `range` object. This function always succeeds.

## Builtin Iterator Types

These are built-in iteration types that are included in Python's C API, but provide no additional functions. They are here for completeness.

PyTypeObject PyReversed_Type

  Part of the Stable ABI.

PyTypeObject PyDictIterKey_Type
  Part of the Stable ABI.

  Part of the Stable ABI Depuis la version 3.8.

PyTypeObject PyDictIterValue_Type
  Part of the Stable ABI.

PyTypeObject PyDictRevIterValue_Type
  Part of the Stable ABI Depuis la version 3.8.

PyTypeObject PyDictIterItem_Type
  Part of the Stable ABI.

PyTypeObject PyDictRevIterItem_Type
  Part of the Stable ABI Depuis la version 3.8.

PyTypeObject PyODictIter_Type

  Type objects for iterators of various built-in objects.

  Do not create instances of these directly; prefer calling `PyObject_GetIter()` instead.

  Note that there is no guarantee that a given built-in type uses a given iterator type. For example, iterating over `range` will use one of two iterator types depending on the size of the range. Other types may start using a similar scheme in the future, without warning.
