Mapping Protocol
- 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).
- 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 the Python expression key in o. 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 the Python expression key in o. 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 list(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 list(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 list(o.items()).
