nuts-flow is largely a thin wrapper around Python’s itertools that allows the chaining of iterators using the >> operator. This leads to more readable code that highlights the flow of data. The following example shows two implementations of a simple data processing pipeline; the first based on itertools and the second using nuts-flow:

>>> from itertools import islice, ifilter
>>> list(islice(ifilter(lambda x: x > 5, xrange(10)), 3))
[6, 7, 8]

>>> from nutsflow import Range, Filter, Take, Collect, _
>>> Range(10) >> Filter(_ > 5) >> Take(3) >> Collect()
[6, 7, 8]

Both examples extract the first three numbers within range [0, 9] that are greater than five. However, the nuts-flow pipeline is easier to understand than the nested itertools code.

nuts-flow is the base for nuts-ml, which is described here .
