defaultdict(default_factory=None, /, [...]) --> 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. All remaining arguments are treated the same as if they were passed to the dict constructor, including keyword arguments.

default_factory Factory for default value called by missing().

Methods

clear

D.clear() -> None. Remove all items from D.

copy

D.copy() -> a shallow copy of D.

fromkeys

Create a new dictionary with keys from iterable and values set to value.

get

Return the value for key if key is in the dictionary, else default.

items

D.items() -> a set-like object providing a view on D's items

keys

D.keys() -> a set-like object providing a view on D's keys

pop

D.pop(k[,d]) -> v, remove specified key and return the corresponding value.

If key is not found, default is returned if given, otherwise KeyError is raised

popitem

Remove and return a (key, value) pair as a 2-tuple.

Pairs are returned in LIFO (last-in, first-out) order. Raises KeyError if the dict is empty.

setdefault

Insert key with a value of default if key is not in the dictionary.

Return the value for key if key is in the dictionary, else default.

update

D.update([E, ]**F) -> None. Update D from dict/iterable E and F. If E is present and has a .keys() method, then does: for k in E: D[k] = E[k] If E is present and lacks a .keys() method, then does: for k, v in E: D[k] = v In either case, this is followed by: for k in F: D[k] = F[k]

values

D.values() -> an object providing a view on D's values

__contains__

True if the dictionary has the specified key, else False.

__eq__

Return self==value.

__ge__

Return self>=value.

__getitem__

x.getitem(y) <==> x[y]

__gt__

Return self>value.

__iter__

Implement iter(self).

__le__

Return self<=value.

__len__

Return len(self).

__lt__

Return self<value.

__ne__

Return self!=value.

__or__

Return self|value.

__ror__

Return value|self.
