bagof-factories

Hint-based factories that build default values at runtime.

Example

>>> from bagof.factories import get_factory
>>> get_factory(list[int])()
[]
>>> get_factory(dict[str, int])()
{}
>>> get_factory(set[int])()
set()
>>> get_factory(int)()
0
>>> get_factory(int | None)()  # optional -> None
>>> get_factory(str)()
''

Abstract collection ABCs (Sequence, Mapping, Set, Iterable, ...), numeric ABCs (numbers.Integral, numbers.Real, ...), enumerations, and builtin/stdlib types whose constructor needs arguments (range, slice, memoryview, datetime, date, uuid.UUID) are all handled too.
