int PyMapping_Check(PyObject *o)
Return 1
if the object provides mapping protocol, and 0
otherwise. This
function always succeeds.
Py_ssize_t PyMapping_Size(PyObject *o)
Py_ssize_t PyMapping_Length(PyObject *o)
Returns the number of keys in object o on success, and -1
on failure. For
objects that do not provide mapping protocol, this is equivalent to the Python
expression len(o)
.
Changed in version 2.5: These functions returned an int
type. This might require
changes in your code for properly supporting 64-bit systems.
int PyMapping_DelItemString(PyObject *o, char *key)
Remove the mapping for object key from the object o. Return -1
on
failure. This is equivalent to the Python statement del o[key]
.
int PyMapping_DelItem(PyObject *o, PyObject *key)
Remove the mapping for object key from the object o. Return -1
on
failure. This is equivalent to the Python statement del o[key]
.
int PyMapping_HasKeyString(PyObject *o, char *key)
On success, return 1
if the mapping object has the key key and 0
otherwise. This is equivalent to o[key]
, returning True
on success
and False
on an exception. This function always succeeds.
int PyMapping_HasKey(PyObject *o, PyObject *key)
Return 1
if the mapping object has the key key and 0
otherwise.
This is equivalent to o[key]
, returning True
on success and False
on an exception. This function always succeeds.
PyObject* PyMapping_Keys(PyObject *o)
Return value: New reference.On success, return a list of the keys in object o. On failure, return NULL.
This is equivalent to the Python expression o.keys()
.
PyObject* PyMapping_Values(PyObject *o)
Return value: New reference.On success, return a list of the values in object o. On failure, return
NULL. This is equivalent to the Python expression o.values()
.
PyObject* PyMapping_Items(PyObject *o)
Return value: New reference.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. This is equivalent to
the Python expression o.items()
.
PyObject* PyMapping_GetItemString(PyObject *o, char *key)
Return value: New reference.Return element of o corresponding to the object key or NULL on failure.
This is the equivalent of the Python expression o[key]
.
int PyMapping_SetItemString(PyObject *o, char *key, PyObject *v)
Map the object key to the value v in object o. Returns -1
on failure.
This is the equivalent of the Python statement o[key] = v
.
