- .. _dict-ops:
- Native dict operations
- ======================
- These ``dict`` operations have fast, optimized implementations. Other
- dictionary operations use generic implementations that are often slower.
- Construction
- ------------
- Construct dict from keys and values:
- * ``{key: value, ...}``
- Construct empty dict:
- * ``{}``
- * ``dict()``
- Construct dict from another object:
- * ``dict(d: dict)``
- * ``dict(x: Iterable)``
- Dict comprehensions:
- * ``{...: ... for ... in ...}``
- * ``{...: ... for ... in ... if ...}``
- Operators
- ---------
- * ``d[key]``
- * ``value in d``
- Statements
- ----------
- * ``d[key] = value``
- * ``for key in d:``
- Methods
- -------
- * ``d.get(key)``
- * ``d.get(key, default)``
- * ``d.keys()``
- * ``d.values()``
- * ``d.items()``
- * ``d.copy()``
- * ``d.clear()``
- * ``d1.update(d2: dict)``
- * ``d.update(x: Iterable)``
- Functions
- ---------
- * ``len(d: dict)``
