class front.tools.FactoryFedSizedIterableContainer(iterable_factory)[source]#

A sized iterable container over the items of iterable_factory(), re-called on every use.

>>> c = FactoryFedSizedIterableContainer(lambda: range(3))
>>> list(c), len(c), 2 in c, 5 in c
([0, 1, 2], 3, True, False)

class front.tools.SizedIterableContainer[source]#

Bases: KvReader

A mapping view of a sequence where the items of the sequence are both keys and values.

>>> vs = ValuesStore([1, 2, 3])
>>> list(vs)
[1, 2, 3]
>>> vs[1]
1
>>> len(vs)
3
>>> 4 in vs
False
