Voir aussi "PyObject_GetItem()", "PyObject_SetItem()" et
"PyObject_DelItem()".

int PyMapping_Check(PyObject *o)
    * Part of the Stable ABI.*

   Return "1" if the object provides the mapping protocol or supports
   slicing, and "0" otherwise.  Note that it returns "1" for Python
   classes with a "__getitem__()" method, since in general it is
   impossible to determine what type of keys the class supports. This
   function always succeeds.

Py_ssize_t PyMapping_Size(PyObject *o)
Py_ssize_t PyMapping_Length(PyObject *o)
    * Part of the Stable ABI.*

   Renvoie le nombre de clefs dans l'objet *o* et "-1" en cas d'échec.
   C'est l'équivalent de l'expression Python "len(o)".

PyObject *PyMapping_GetItemString(PyObject *o, const char *key)
    *Valeur de retour : nouvelle référence.** Part of the Stable ABI.*

   This is the same as "PyObject_GetItem()", but *key* is specified as
   a const char* UTF-8 encoded bytes string, rather than a PyObject*.

int PyMapping_GetOptionalItem(PyObject *obj, PyObject *key, PyObject **result)
    * Part of the Stable ABI since version 3.13.*

   Variant of "PyObject_GetItem()" which doesn't raise "KeyError" if
   the key is not found.

   If the key is found, return "1" and set **result* to a new *strong
   reference* to the corresponding value. If the key is not found,
   return "0" and set **result* to "NULL"; the "KeyError" is silenced.
   If an error other than "KeyError" is raised, return "-1" and set
   **result* to "NULL".

   Ajouté dans la version 3.13.

int PyMapping_GetOptionalItemString(PyObject *obj, const char *key, PyObject **result)
    * Part of the Stable ABI since version 3.13.*

   This is the same as "PyMapping_GetOptionalItem()", but *key* is
   specified as a const char* UTF-8 encoded bytes string, rather than
   a PyObject*.

   Ajouté dans la version 3.13.

int PyMapping_SetItemString(PyObject *o, const char *key, PyObject *v)
    * Part of the Stable ABI.*

   This is the same as "PyObject_SetItem()", but *key* is specified as
   a const char* UTF-8 encoded bytes string, rather than a PyObject*.

int PyMapping_DelItem(PyObject *o, PyObject *key)

   This is an alias of "PyObject_DelItem()".

int PyMapping_DelItemString(PyObject *o, const char *key)

   This is the same as "PyObject_DelItem()", but *key* is specified as
   a const char* UTF-8 encoded bytes string, rather than a PyObject*.

int PyMapping_HasKeyWithError(PyObject *o, PyObject *key)
    * Part of the Stable ABI since version 3.13.*

   Return "1" if the mapping object has the key *key* and "0"
   otherwise. This is equivalent to the Python expression "key in o".
   On failure, return "-1".

   Ajouté dans la version 3.13.

int PyMapping_HasKeyStringWithError(PyObject *o, const char *key)
    * Part of the Stable ABI since version 3.13.*

   This is the same as "PyMapping_HasKeyWithError()", but *key* is
   specified as a const char* UTF-8 encoded bytes string, rather than
   a PyObject*.

   Ajouté dans la version 3.13.

int PyMapping_HasKey(PyObject *o, PyObject *key)
    * Part of the Stable ABI.*

   Renvoie "1" si l'objet de correspondance possède une clef *key* et
   "0" sinon. C'est l'équivalent de l'expression Python "key in o".
   Cette fonction ne provoque jamais d'erreur.

   Note:

     Exceptions which occur when this calls "__getitem__()" method are
     silently ignored. For proper error handling, use
     "PyMapping_HasKeyWithError()", "PyMapping_GetOptionalItem()" or
     "PyObject_GetItem()" instead.

int PyMapping_HasKeyString(PyObject *o, const char *key)
    * Part of the Stable ABI.*

   This is the same as "PyMapping_HasKey()", but *key* is specified as
   a const char* UTF-8 encoded bytes string, rather than a PyObject*.

   Note:

     Exceptions that occur when this calls "__getitem__()" method or
     while creating the temporary "str" object are silently ignored.
     For proper error handling, use
     "PyMapping_HasKeyStringWithError()",
     "PyMapping_GetOptionalItemString()" or
     "PyMapping_GetItemString()" instead.

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

   Renvoie la liste des clefs dans l'objet *o*. En cas d'échec,
   renvoie *NULL*.

   Modifié dans la version 3.7: Auparavant, la fonction renvoyait une
   liste ou un *n*-uplet.

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

   Renvoie la liste des valeurs dans l'objet *o*. En cas d'échec,
   renvoie *NULL*.

   Modifié dans la version 3.7: Auparavant, la fonction renvoyait une
   liste ou un *n*-uplet.

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

   Renvoie la liste des éléments dans l'objet *o*, où chaque élément
   est un n-uplet contenant une paire clef-valeur. En cas d'échec,
   renvoie *NULL*.

   Modifié dans la version 3.7: Auparavant, la fonction renvoyait une
   liste ou un *n*-uplet.
