iterplus 0.2.5

iterplus provides functionality that extends itertools

iterplus - itertools extended

This library provides a set of functions that complement Python itertools. These include means to access iterable content via slicing, scan generator (easy series) and chainable wrapper (ie. a.map(…).filter(…)).

Examples

Scan

fibo = scan(0, 1, lambda a, b: a + b)

“scan” returns an iterator. Note how simple it’s to define series such as Fibonacci’s using it. In case an explicit rule is not provided, it infers one automatically (ie. 1,2,3,…).

Sliceable

sliceable(scan(0, 1))[2:5] # returns list containing third, fourth and fifth item

“sliceable” makes it possible to slice the content of iterators.

Chainable

chainable([1, 2, 3]).map(lambda x: x * 2).filter(lambda x: x > 3).val() == [4, 6]

“chainable” makes it possible to use basic functional utilities (map, filter, reduce) using a chaining syntax.
