.. _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)``
