defaultdict(default_factory) --> dict with default factory

The default factory is called without arguments to produce a new value when a key is not present, in __getitem__ only. A defaultdict compares equal to a dict with the same items.

Instance Methods

[hide private]

a shallow copy of D.

__copy__(D)

__getattribute__(...)
x.__getattribute__('name') <==> x.name

new empty dictionary

__init__(...)
x.__init__(...) initializes x; see x.__class__.__doc__ for signature

__missing__(...)
__missing__(key) # Called by __getitem__ for missing key; pseudo-code: if self.default_factory is None: raise KeyError((key,)) self[key] = value = self.default_factory() return value

__reduce__(...)
Return state information for pickling.

__repr__(x)
repr(x)

a shallow copy of D.

copy(D)
