매핑 프로토콜

PyObject_GetItem(), PyObject_SetItem() 및 PyObject_DelItem()도 참조하십시오.

int PyMapping_Check(PyObject *o)

Part of the Stable ABI.

Return 1 if the object provides the mapping protocol or supports slicing, and 0 otherwise. Note that it returns 1 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.

성공 시 객체 o의 키 수를 반환하고, 실패하면 -1을 반환합니다. 이는 파이썬 표현식 len(o)와 동등합니다.

PyObject *PyMapping_GetItemString(PyObject *o, const char *key)

Return value: New reference. 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 raise KeyError 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, return 0 and set *result to NULL; the KeyError is silenced. If an error other than KeyError is raised, return -1 and set *result to NULL.

Added in 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*.

Added in 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 and 0 otherwise. This is equivalent to the Python expression key in o. On failure, return -1.

Added in 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*.

Added in version 3.13.

int PyMapping_HasKey(PyObject *o, PyObject *key)

Part of the Stable ABI.

매핑 객체에 key 키가 있으면 1을 반환하고, 그렇지 않으면 0을 반환합니다. 이는 파이썬 표현식 key in o와 동등합니다. 이 함수는 항상 성공합니다.

참고

Exceptions which occur when this calls __getitem__() method are silently ignored. For proper error handling, use PyMapping_HasKeyWithError(), PyMapping_GetOptionalItem() or PyObject_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*.

참고

Exceptions that occur when this calls __getitem__() method or while creating the temporary str object are silently ignored. For proper error handling, use PyMapping_HasKeyStringWithError(), PyMapping_GetOptionalItemString() or PyMapping_GetItemString() instead.

PyObject *PyMapping_Keys(PyObject *o)

Return value: New reference. Part of the Stable ABI.

성공하면, 객체 o의 키 리스트를 반환합니다. 실패하면, NULL을 반환합니다.

버전 3.7에서 변경: 이전에는 함수가 리스트나 튜플을 반환했습니다.

PyObject *PyMapping_Values(PyObject *o)

Return value: New reference. Part of the Stable ABI.

성공하면, 객체 o의 값 리스트를 반환합니다. 실패하면, NULL을 반환합니다.

버전 3.7에서 변경: 이전에는 함수가 리스트나 튜플을 반환했습니다.

PyObject *PyMapping_Items(PyObject *o)

Return value: New reference. Part of the Stable ABI.

성공하면, 객체 o에 있는 항목 리스트를 반환합니다. 여기서 각 항목은 키-값 쌍을 포함하는 튜플입니다. 실패하면, NULL을 반환합니다.

버전 3.7에서 변경: 이전에는 함수가 리스트나 튜플을 반환했습니다.
