int PyMapping_Check(PyObject *o)¶
- Part of the Stable ABI.
Return
1
if the object provides the mapping protocol or supports slicing, and0
otherwise. Note that it returns1
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 Pythonlen(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 raiseKeyError
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, return0
and set *result toNULL
; theKeyError
is silenced. If an error other thanKeyError
is raised, return-1
and set *result toNULL
.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 and0
otherwise. This is equivalent to the Python expressionkey 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 et0
sinon. C'est l'équivalent de l'expression Pythonkey 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, usePyMapping_HasKeyWithError()
,PyMapping_GetOptionalItem()
orPyObject_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 temporarystr
object are silently ignored. For proper error handling, usePyMapping_HasKeyStringWithError()
,PyMapping_GetOptionalItemString()
orPyMapping_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.
