Mapping Protocol¶
See also PyObject_GetItem()
, PyObject_SetItem()
and
PyObject_DelItem()
.
-
int PyMapping_Check(PyObject *o)¶
- Część stabilnego 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)¶
- Część stabilnego ABI.
Returns the number of keys in object o on success, and
-1
on failure. This is equivalent to the Python expressionlen(o)
.
-
PyObject *PyMapping_GetItemString(PyObject *o, const char *key)¶
- Wartość zwracana: nowa referencja. Część stabilnego 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_SetItemString(PyObject *o, const char *key, PyObject *v)¶
- Część stabilnego 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_HasKey(PyObject *o, PyObject *key)¶
- Część stabilnego ABI.
Return
1
if the mapping object has the key key and0
otherwise. This is equivalent to the Python expressionkey in o
. This function always succeeds.Informacja
Exceptions which occur when this calls
__getitem__()
method are silently ignored. For proper error handling, usePyObject_GetItem()
instead.
-
int PyMapping_HasKeyString(PyObject *o, const char *key)¶
- Część stabilnego 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*.Informacja
Exceptions that occur when this calls
__getitem__()
method or while creating the temporarystr
object are silently ignored. For proper error handling, usePyMapping_GetItemString()
instead.
-
PyObject *PyMapping_Keys(PyObject *o)¶
- Wartość zwracana: nowa referencja. Część stabilnego ABI.
On success, return a list of the keys in object o. On failure, return
NULL
.Zmienione w wersji 3.7: Previously, the function returned a list or a tuple.
-
PyObject *PyMapping_Values(PyObject *o)¶
- Wartość zwracana: nowa referencja. Część stabilnego ABI.
On success, return a list of the values in object o. On failure, return
NULL
.Zmienione w wersji 3.7: Previously, the function returned a list or a tuple.
-
PyObject *PyMapping_Items(PyObject *o)¶
- Wartość zwracana: nowa referencja. Część stabilnego ABI.
On success, return a list of the items in object o, where each item is a tuple containing a key-value pair. On failure, return
NULL
.Zmienione w wersji 3.7: Previously, the function returned a list or a tuple.
