# Dictionary objects

type PyDictObject

  이 `PyObject`의 서브 형은 파이썬 딕셔너리 객체를 나타냅니다.

PyTypeObject PyDict_Type
  Part of the 안정 ABI.

  이 `PyTypeObject` 인스턴스는 파이썬 딕셔너리 형을 나타냅니다. 이것은 파이썬 계층의 `dict`와 같은 객체입니다.

int PyDict_Check( PyObject *p)
  Thread safety: Atomic.

  p가 dict 객체이거나 dict 형의 서브 형의 인스턴스면 참을 반환합니다. 이 함수는 항상 성공합니다.

int PyDict_CheckExact( PyObject *p)
  Thread safety: Atomic.

  p가 dict 객체이지만, dict 형의 서브 형의 인스턴스는 아니면 참을 반환합니다. 이 함수는 항상 성공합니다.

PyObject *PyDict_New()
  반환값: 새 참조. Part of the 안정 ABI. Thread safety: Atomic.

  새로운 빈 딕셔너리를 반환하거나, 실패하면 `NULL`을 반환합니다.

PyObject *PyDictProxy_New( PyObject *mapping)
  반환값: 새 참조. Part of the 안정 ABI.

  읽기 전용 동작을 강제하는 매핑을 위한 `types.MappingProxyType` 객체를 반환합니다. 이것은 일반적으로 비 동적 클래스 형을 위한 딕셔너리의 수정을 방지하기 위해 뷰를 만드는 데 사용됩니다.

  The first argument can be a `dict`, a `frozendict`, or a mapping.

  버전 3.15에서 변경: Also accept `frozendict`.

PyTypeObject PyDictProxy_Type
  Part of the 안정 ABI.

  The type object for mapping proxy objects created by `PyDictProxy_New()` and for the read-only `__dict__` attribute of many built-in types. A `PyDictProxy_Type` instance provides a dynamic, read-only view of an underlying dictionary: changes to the underlying dictionary are reflected in the proxy, but the proxy itself does not support mutation operations. This corresponds to `types.MappingProxyType` in Python.

void PyDict_Clear( PyObject *p)
  Part of the 안정 ABI. Thread safety: Atomic.

  기존 딕셔너리의 모든 키-값 쌍을 비웁니다.

  Do nothing if the argument is not a `dict` or a `dict` subclass.

int PyDict_Contains( PyObject *p, PyObject *key)
  Part of the 안정 ABI. Thread safety: Safe for concurrent use on the same object.

  Determine if dictionary p contains key. If an item in p matches key, return `1`, otherwise return `0`. On error, return `-1`. This is equivalent to the Python expression `key in p`.

  The first argument can be a `dict` or a `frozendict`.

  참고

  The operation is atomic on free threading when key is `str`, `int`, `float`, `bool` or `bytes`.

  버전 3.15에서 변경: Also accept `frozendict`.

int PyDict_ContainsString( PyObject *p, const char *key)
  Thread safety: Atomic.

  이것은 `PyDict_Contains()`와 같지만, key가 PyObject *가 아닌 const char* UTF-8 인코딩된 바이트 문자열로 지정됩니다.

  The first argument can be a `dict` or a `frozendict`.

  Added in version 3.13.

  버전 3.15에서 변경: Also accept `frozendict`.

PyObject *PyDict_Copy( PyObject *p)
  반환값: 새 참조. Part of the 안정 ABI. Thread safety: Atomic.

  p와 같은 키-값 쌍을 포함하는 새 딕셔너리를 반환합니다.

int PyDict_SetItem( PyObject *p, PyObject *key, PyObject *val)
  Part of the 안정 ABI. Thread safety: Safe for concurrent use on the same object.

  딕셔너리 p에 val을 key 키로 삽입합니다. key는 해시 가능해야 합니다. 그렇지 않으면 `TypeError`가 발생합니다. 성공하면 `0`을, 실패하면 `-1`을 반환합니다. 이 함수는 val에 대한 참조를 훔치지 않습니다.

  참고

  The operation is atomic on free threading when key is `str`, `int`, `float`, `bool` or `bytes`.

int PyDict_SetItemString( PyObject *p, const char *key, PyObject *val)
  Part of the 안정 ABI. Thread safety: Atomic.

  이것은 `PyDict_SetItem()`와 같지만, key가 PyObject *가 아닌 const char* UTF-8 인코딩된 바이트 문자열로 지정됩니다.

int PyDict_DelItem( PyObject *p, PyObject *key)
  Part of the 안정 ABI. Thread safety: Safe for concurrent use on the same object.

  딕셔너리 p에서 키가 key인 항목을 제거합니다. key는 해시 가능해야 합니다. 그렇지 않으면 `TypeError`가 발생합니다. key가 딕셔너리에 없으면, `KeyError`가 발생합니다. 성공하면 `0`을, 실패하면 `-1`을 반환합니다.

  참고

  The operation is atomic on free threading when key is `str`, `int`, `float`, `bool` or `bytes`.

int PyDict_DelItemString( PyObject *p, const char *key)
  Part of the 안정 ABI. Thread safety: Atomic.

  이것은 `PyDict_DelItem()`와 같지만, key가 PyObject *가 아닌 const char* UTF-8 인코딩된 바이트 문자열로 지정됩니다.

int PyDict_GetItemRef( PyObject *p, PyObject *key, PyObject **result)
  Part of the 안정 ABI 버전 3.13 이후로. Thread safety: Safe for concurrent use on the same object.

  Return a new strong reference to the object from dictionary p which has a key key:

  - If the key is present, set *result to a new strong reference to the value and return `1`.

  - If the key is missing, set *result to `NULL` and return `0`.

  - On error, raise an exception, set *result to `NULL` and return `-1`.

  The first argument can be a `dict` or a `frozendict`.

  참고

  The operation is atomic on free threading when key is `str`, `int`, `float`, `bool` or `bytes`.

  Added in version 3.13.

  버전 3.15에서 변경: Also accept `frozendict`.

  See also the `PyObject_GetItem()` function.

PyObject *PyDict_GetItem( PyObject *p, PyObject *key)
  반환값: 빌린 참조. Part of the 안정 ABI. Thread safety: Safe to call from multiple threads with external synchronization only.

  딕셔너리 p에서 키가 key인 객체에 대한 빌린 참조를 반환합니다. key 키가 없으면 예외를 설정하지 않고 `NULL`을 반환합니다.

  The first argument can be a `dict` or a `frozendict`.

  참고

  `__hash__()`와 `__eq__()` 메서드를 호출하는 동안 발생하는 예외는 조용히 무시됩니다. 대신 `PyDict_GetItemWithError()` 함수를 사용하십시오.

  참고

  In the free-threaded build, the returned borrowed reference may become invalid if another thread modifies the dictionary concurrently. Prefer `PyDict_GetItemRef()`, which returns a strong reference.

  버전 3.10에서 변경: Calling this API without an attached thread state had been allowed for historical reason. It is no longer allowed.

  버전 3.15에서 변경: Also accept `frozendict`.

PyObject *PyDict_GetItemWithError( PyObject *p, PyObject *key)
  반환값: 빌린 참조. Part of the 안정 ABI. Thread safety: Safe to call from multiple threads with external synchronization only.

  예외를 억제하지 않는 `PyDict_GetItem()`의 변형입니다. 예외가 발생하면 예외를 설정하고 `NULL`을 반환합니다. 키가 없으면 예외를 설정하지 않고 `NULL`을 반환합니다.

  참고

  In the free-threaded build, the returned borrowed reference may become invalid if another thread modifies the dictionary concurrently. Prefer `PyDict_GetItemRef()`, which returns a strong reference.

  버전 3.15에서 변경: Also accept `frozendict`.

PyObject *PyDict_GetItemString( PyObject *p, const char *key)
  반환값: 빌린 참조. Part of the 안정 ABI. Thread safety: Safe to call from multiple threads with external synchronization only.

  이것은 `PyDict_GetItem()`와 같지만, key가 PyObject *가 아닌 const char* UTF-8로 인코딩된 바이트 문자열로 지정됩니다.

  참고

  `__hash__()`와 `__eq__()` 메서드를 호출하는 동안이나 임시 `str` 객체를 만드는 동안 발생하는 예외는 조용히 무시됩니다. 대신 자체 `PyUnicode_FromString()` key와 함께 `PyDict_GetItemWithError()` 함수를 사용하는 것이 좋습니다.

  참고

  In the free-threaded build, the returned borrowed reference may become invalid if another thread modifies the dictionary concurrently. Prefer `PyDict_GetItemStringRef()`, which returns a strong reference.

  버전 3.15에서 변경: Also accept `frozendict`.

int PyDict_GetItemStringRef( PyObject *p, const char *key, PyObject **result)
  Part of the 안정 ABI 버전 3.13 이후로. Thread safety: Atomic.

  이것은 `PyDict_GetItemRef()`와 유시하지만, key가 PyObject *가 아닌 const char* UTF-8로 인코딩된 바이트 문자열로 지정됩니다.

  Added in version 3.13.

  버전 3.15에서 변경: Also accept `frozendict`.

PyObject *PyDict_SetDefault( PyObject *p, PyObject *key, PyObject *defaultobj)
  반환값: 빌린 참조. Thread safety: Safe to call from multiple threads with external synchronization only.

  이것은 파이썬 수준의 `dict.setdefault()`와 같습니다. 존재하면, 딕셔너리 p에서 key에 해당하는 값을 반환합니다. 키가 dict에 없으면, 값 defaultobj로 삽입되고, defaultobj가 반환됩니다. 이 함수는 key의 해시 함수를 조회 및 삽입을 위해 독립적으로 평가하는 대신 한 번만 평가합니다.

  Added in version 3.4.

  참고

  In the free-threaded build, the returned borrowed reference may become invalid if another thread modifies the dictionary concurrently. Prefer `PyDict_SetDefaultRef()`, which returns a strong reference.

int PyDict_SetDefaultRef( PyObject *p, PyObject *key, PyObject *default_value, PyObject **result)
  Part of the 안정 ABI 버전 3.15 이후로. Thread safety: Safe for concurrent use on the same object.

  Inserts default_value into the dictionary p with a key of key if the key is not already present in the dictionary. If result is not `NULL`, then *result is set to a strong reference to either default_value, if the key was not present, or the existing value, if key was already present in the dictionary. Returns `1` if the key was present and default_value was not inserted, or `0` if the key was not present and default_value was inserted. On failure, returns `-1`, sets an exception, and sets `*result` to `NULL`.

  For clarity: if you have a strong reference to default_value before calling this function, then after it returns, you hold a strong reference to both default_value and *result (if it’s not `NULL`). These may refer to the same object: in that case you hold two separate references to it.

  참고

  The operation is atomic on free threading when key is `str`, `int`, `float`, `bool` or `bytes`.

  Added in version 3.13.

int PyDict_Pop( PyObject *p, PyObject *key, PyObject **result)
  Thread safety: Safe for concurrent use on the same object.

  Remove key from dictionary p and optionally return the removed value. Do not raise `KeyError` if the key is missing.

  - If the key is present, set *result to a new reference to the removed value if result is not `NULL`, and return `1`.

  - If the key is missing, set *result to `NULL` if result is not `NULL`, and return `0`.

  - On error, raise an exception and return `-1`.

  Similar to `dict.pop()`, but without the default value and not raising `KeyError` if the key is missing.

  참고

  The operation is atomic on free threading when key is `str`, `int`, `float`, `bool` or `bytes`.

  Added in version 3.13.

int PyDict_PopString( PyObject *p, const char *key, PyObject **result)
  Thread safety: Atomic.

  이것은 `PyDict_Pop()`와 유사하지만, key가 PyObject *가 아닌 const char* UTF-8로 인코딩된 바이트 문자열로 지정됩니다.

  Added in version 3.13.

PyObject *PyDict_Items( PyObject *p)
  반환값: 새 참조. Part of the 안정 ABI. Thread safety: Atomic.

  딕셔너리의 모든 항목을 포함하는 `PyListObject`를 반환합니다.

  The first argument can be a `dict` or a `frozendict`.

  버전 3.15에서 변경: Also accept `frozendict`.

PyObject *PyDict_Keys( PyObject *p)
  반환값: 새 참조. Part of the 안정 ABI. Thread safety: Atomic.

  딕셔너리의 모든 키를 포함하는 `PyListObject`를 반환합니다.

  The first argument can be a `dict` or a `frozendict`.

  버전 3.15에서 변경: Also accept `frozendict`.

PyObject *PyDict_Values( PyObject *p)
  반환값: 새 참조. Part of the 안정 ABI. Thread safety: Atomic.

  딕셔너리 p의 모든 값을 포함하는 `PyListObject`를 반환합니다.

  The first argument can be a `dict` or a `frozendict`.

  버전 3.15에서 변경: Also accept `frozendict`.

Py_ssize_t PyDict_Size( PyObject *p)
  Part of the 안정 ABI. Thread safety: Atomic.

  딕셔너리에 있는 항목의 수를 반환합니다. 이는 딕셔너리에 대한 `len(p)`와 동등합니다.

  The argument can be a `dict` or a `frozendict`.

  버전 3.15에서 변경: Also accept `frozendict`.

Py_ssize_t PyDict_GET_SIZE( PyObject *p)
  Thread safety: Atomic.

  Similar to `PyDict_Size()`, but without error checking.

  버전 3.15에서 변경: Also accept `frozendict`.

int PyDict_Next( PyObject *p, Py_ssize_t *ppos, PyObject **pkey, PyObject **pvalue)
  Part of the 안정 ABI. Thread safety: Safe to call from multiple threads with external synchronization only.

  딕셔너리 p의 모든 키-값 쌍을 이터레이트 합니다. ppos에 의해 참조된 `Py_ssize_t`는, 이터레이션을 시작하기 위해 이 함수를 처음 호출하기 전에 `0`으로 초기화되어야 합니다; 이 함수는 딕셔너리의 각 쌍에 대해 참을 반환하고, 모든 쌍이 보고되었으면 거짓을 반환합니다. 매개 변수 pkey와 pvalue는 각각 키와 값으로 채울 PyObject * 변수를 가리 키거나, `NULL` 일 수 있습니다. 이들을 통해 반환된 참조는 모두 빌린(borrowed) 것입니다. 이터레이션 중에 ppos를 변경하면 안 됩니다. 이 값은 내부 딕셔너리 구조 내의 오프셋을 나타내며, 구조가 희박하므로 오프셋이 연속되지 않습니다.

  The first argument can be a `dict` or a `frozendict`.

  예를 들면:

      PyObject *key, *value;
      Py_ssize_t pos = 0;

      while (PyDict_Next(self->dict, &pos, &key, &value)) {
          /* 값으로 흥미로운 작업을 수행합니다... */
          ...
      }

  딕셔너리 p는 이터레이션 중에 변경해서는 안 됩니다. 딕셔너리를 이터레이트 할 때 값을 변경하는 것은 안전하지만, 키 집합이 변경되지 않는 한만 그렇습니다. 예를 들면:

      PyObject *key, *value;
      Py_ssize_t pos = 0;

      while (PyDict_Next(self->dict, &pos, &key, &value)) {
          long i = PyLong_AsLong(value);
          if (i == -1 && PyErr_Occurred()) {
              return -1;
          }
          PyObject *o = PyLong_FromLong(i + 1);
          if (o == NULL)
              return -1;
          if (PyDict_SetItem(self->dict, key, o) < 0) {
              Py_DECREF(o);
              return -1;
          }
          Py_DECREF(o);
      }

  The function is not thread-safe in the free-threaded build without external synchronization for a mutable `dict`. You can use `Py_BEGIN_CRITICAL_SECTION` to lock the dictionary while iterating over it:

      Py_BEGIN_CRITICAL_SECTION(self->dict);
      while (PyDict_Next(self->dict, &pos, &key, &value)) {
          ...
      }
      Py_END_CRITICAL_SECTION();

  The function is thread-safe on a `frozendict`.

  참고

  On the free-threaded build, this function can be used safely inside a critical section. However, the references returned for pkey and pvalue are borrowed and are only valid while the critical section is held. If you need to use these objects outside the critical section or when the critical section can be suspended, create a strong reference (for example, using `Py_NewRef()`).

  버전 3.15에서 변경: Also accept `frozendict`.

int PyDict_Merge( PyObject *a, PyObject *b, int override)
  Part of the 안정 ABI. Thread safety: Safe for concurrent use on the same object.

  매핑 객체 b를 이터레이트 하면서, 키-값 쌍을 딕셔너리 a에 추가합니다. b는 딕셔너리거나 `PyMapping_Keys()`와 `PyObject_GetItem()`를 지원하는 모든 객체일 수 있습니다. override가 참이면, a에 있는 기존 쌍이 b에서 일치하는 키가 있으면 교체되고, 그렇지 않으면 a와 일치하는 키가 없을 때만 쌍이 추가됩니다. 성공하면 `0`을 반환하고, 예외가 발생하면 `-1`을 반환합니다.

  참고

  In the free-threaded build, when b is a `dict` (with the standard iterator), both a and b are locked for the duration of the operation. When b is a non-dict mapping, only a is locked; b may be concurrently modified by another thread.

int PyDict_Update( PyObject *a, PyObject *b)
  Part of the 안정 ABI. Thread safety: Safe for concurrent use on the same object.

  이는 C에서 `PyDict_Merge(a, b, 1)`와 같고, 두 번째 인자에 “keys” 어트리뷰트가 없을 때 `PyDict_Update()`가 키-값 쌍의 시퀀스에 대해 이터레이트 하지 않는다는 점만 제외하면, 파이썬에서 `a.update(b)`와 유사합니다. 성공하면 `0`을 반환하고, 예외가 발생하면 `-1`을 반환합니다.

  참고

  In the free-threaded build, when b is a `dict` (with the standard iterator), both a and b are locked for the duration of the operation. When b is a non-dict mapping, only a is locked; b may be concurrently modified by another thread.

int PyDict_MergeFromSeq2( PyObject *a, PyObject *seq2, int override)
  Part of the 안정 ABI. Thread safety: Safe for concurrent use on the same object.

  seq2의 키-값 쌍으로 딕셔너리 a를 갱신하거나 병합합니다. seq2는 키-값 쌍으로 간주하는 길이 2의 이터러블 객체를 생성하는 이터러블 객체여야 합니다. 중복 키가 있으면, override가 참이면 마지막이 승리하고, 그렇지 않으면 첫 번째가 승리합니다. 성공 시 `0`을 반환하고, 예외가 발생하면 `-1`을 반환합니다. 동등한 파이썬은 이렇습니다(반환 값 제외)

      def PyDict_MergeFromSeq2(a, seq2, override):
          for key, value in seq2:
              if override or key not in a:
                  a[key] = value

  참고

  In the free-threaded build, only a is locked. The iteration over seq2 is not synchronized; seq2 may be concurrently modified by another thread.

int PyDict_AddWatcher( PyDict_WatchCallback callback)
  Thread safety: Safe to call from multiple threads with external synchronization only.

  Register callback as a dictionary watcher. Return a non-negative integer id which must be passed to future calls to `PyDict_Watch()`. In case of error (e.g. no more watcher IDs available), return `-1` and set an exception.

  참고

  This function is not internally synchronized. In the free-threaded build, callers should ensure no concurrent calls to `PyDict_AddWatcher()` or `PyDict_ClearWatcher()` are in progress.

  Added in version 3.12.

int PyDict_ClearWatcher(int watcher_id)
  Thread safety: Safe to call from multiple threads with external synchronization only.

  Clear watcher identified by watcher_id previously returned from `PyDict_AddWatcher()`. Return `0` on success, `-1` on error (e.g. if the given watcher_id was never registered.)

  참고

  This function is not internally synchronized. In the free-threaded build, callers should ensure no concurrent calls to `PyDict_AddWatcher()` or `PyDict_ClearWatcher()` are in progress.

  Added in version 3.12.

int PyDict_Watch(int watcher_id, PyObject *dict)
  Thread safety: Safe to call without external synchronization on distinct objects.

  Mark dictionary dict as watched. The callback granted watcher_id by `PyDict_AddWatcher()` will be called when dict is modified or deallocated. Return `0` on success or `-1` on error.

  Added in version 3.12.

int PyDict_Unwatch(int watcher_id, PyObject *dict)
  Thread safety: Safe to call without external synchronization on distinct objects.

  Mark dictionary dict as no longer watched. The callback granted watcher_id by `PyDict_AddWatcher()` will no longer be called when dict is modified or deallocated. The dict must previously have been watched by this watcher. Return `0` on success or `-1` on error.

  Added in version 3.12.

type PyDict_WatchEvent

  Enumeration of possible dictionary watcher events: `PyDict_EVENT_ADDED`, `PyDict_EVENT_MODIFIED`, `PyDict_EVENT_DELETED`, `PyDict_EVENT_CLONED`, `PyDict_EVENT_CLEARED`, or `PyDict_EVENT_DEALLOCATED`.

  Added in version 3.12.

typedef int (*PyDict_WatchCallback)( PyDict_WatchEvent event, PyObject *dict, PyObject *key, PyObject *new_value)

  Type of a dict watcher callback function.

  If event is `PyDict_EVENT_CLEARED` or `PyDict_EVENT_DEALLOCATED`, both key and new_value will be `NULL`. If event is `PyDict_EVENT_ADDED` or `PyDict_EVENT_MODIFIED`, new_value will be the new value for key. If event is `PyDict_EVENT_DELETED`, key is being deleted from the dictionary and new_value will be `NULL`.

  `PyDict_EVENT_CLONED` occurs when dict was previously empty and another dict is merged into it. To maintain efficiency of this operation, per-key `PyDict_EVENT_ADDED` events are not issued in this case; instead a single `PyDict_EVENT_CLONED` is issued, and key will be the source dictionary.

  The callback may inspect but must not modify dict; doing so could have unpredictable effects, including infinite recursion. Do not trigger Python code execution in the callback, as it could modify the dict as a side effect.

  If event is `PyDict_EVENT_DEALLOCATED`, taking a new reference in the callback to the about-to-be-destroyed dictionary will resurrect it and prevent it from being freed at this time. When the resurrected object is destroyed later, any watcher callbacks active at that time will be called again.

  Callbacks occur before the notified modification to dict takes place, so the prior state of dict can be inspected.

  If the callback sets an exception, it must return `-1`; this exception will be printed as an unraisable exception using `PyErr_WriteUnraisable()`. Otherwise it should return `0`.

  There may already be a pending exception set on entry to the callback. In this case, the callback should return `0` with the same exception still set. This means the callback may not call any other API that can set an exception unless it saves and clears the exception state first, and restores it before returning.

  Added in version 3.12.

## Dictionary view objects

int PyDictViewSet_Check( PyObject *op)

  Return true if op is a view of a set inside a dictionary. This is currently equivalent to PyDictKeys_Check ( op ) || PyDictItems_Check (op). This function always succeeds.

PyTypeObject PyDictKeys_Type
  Part of the 안정 ABI.

  Type object for a view of dictionary keys. In Python, this is the type of the object returned by `dict.keys()`.

  Return true if op is an instance of a dictionary items view. This function always succeeds.

## Frozen dictionary objects

Added in version 3.15.

PyTypeObject PyFrozenDict_Type

  This instance of `PyTypeObject` represents the Python frozen dictionary type. This is the same object as `frozendict` in the Python layer.

int PyAnyDict_Check( PyObject *p)

  Return true if p is a `dict` object, a `frozendict` object, or an instance of a subtype of the `dict` or `frozendict` type. This function always succeeds.

int PyAnyDict_CheckExact( PyObject *p)

PyObject *PyFrozenDict_New( PyObject *iterable)

  Return a new `frozendict` from an iterable, or `NULL` on failure with an exception set.

  Create an empty dictionary if iterable is `NULL`.

## Ordered dictionaries

Python’s C API provides interface for `collections.OrderedDict` from C. Since Python 3.7, dictionaries are ordered by default, so there is usually little need for these functions; prefer `PyDict*` where possible.

PyTypeObject PyODict_Type

  Type object for ordered dictionaries. This is the same object as `collections.OrderedDict` in the Python layer.

int PyODict_Check( PyObject *od)

  Return true if od is an ordered dictionary object or an instance of a subtype of the `OrderedDict` type. This function always succeeds.

int PyODict_CheckExact( PyObject *od)

  Return true if od is an ordered dictionary object, but not an instance of a subtype of the `OrderedDict` type. This function always succeeds.

PyTypeObject PyODictKeys_Type

  Analogous to `PyDictKeys_Type` for ordered dictionaries.

PyTypeObject PyODictValues_Type

  Analogous to `PyDictValues_Type` for ordered dictionaries.

PyTypeObject PyODictItems_Type

  Analogous to `PyDictItems_Type` for ordered dictionaries.

PyObject *PyODict_New(void)

  Return a new empty ordered dictionary, or `NULL` on failure.

  This is analogous to `PyDict_New()`.

int PyODict_SetItem( PyObject *od, PyObject *key, PyObject *value)

  Insert value into the ordered dictionary od with a key of key. Return `0` on success or `-1` with an exception set on failure.

  This is analogous to `PyDict_SetItem()`.

int PyODict_DelItem( PyObject *od, PyObject *key)

  Remove the entry in the ordered dictionary od with key key. Return `0` on success or `-1` with an exception set on failure.

  This is analogous to `PyDict_DelItem()`.

These are soft deprecated aliases to `PyDict` APIs:

`PyODict` | `PyDict`

PyODict_GetItem(od, key)

`PyDict_GetItem()`

PyODict_GetItemWithError(od, key)

`PyDict_GetItemWithError()`

PyODict_GetItemString(od, key)
