Mapping Protocol¶
- 
int PyMapping_Check(PyObject *o)¶
- Return - 1if the object provides mapping protocol, and- 0otherwise. 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 - -1on failure. For objects that do not provide mapping protocol, this is equivalent to the Python expression- len(o).
- 
int PyMapping_DelItemString(PyObject *o, const char *key)¶
- Remove the mapping for object key from the object o. Return - -1on 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 - -1on failure. This is equivalent to the Python statement- del o[key].
- 
int PyMapping_HasKeyString(PyObject *o, const char *key)¶
- On success, return - 1if the mapping object has the key key and- 0otherwise. This is equivalent to the Python expression- key in o. This function always succeeds.
- 
int PyMapping_HasKey(PyObject *o, PyObject *key)¶
- Return - 1if the mapping object has the key key and- 0otherwise. This is equivalent to the Python expression- key in o. This function always succeeds.
- 
PyObject* PyMapping_Keys(PyObject *o)¶
- Return value: New reference.On success, return a list or tuple of the keys in object o. On failure, return NULL. 
- 
PyObject* PyMapping_Values(PyObject *o)¶
- Return value: New reference.On success, return a list or tuple of the values in object o. On failure, return NULL. 
- 
PyObject* PyMapping_Items(PyObject *o)¶
- Return value: New reference.On success, return a list or tuple of the items in object o, where each item is a tuple containing a key-value pair. On failure, return NULL.
