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 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)
