More Itertools

https://readthedocs.org/projects/more-itertools/badge/?version=latest

Python's itertools library is a gem - you can compose elegant
solutions for a variety of problems with the functions it provides.
In more-itertools we collect additional building blocks, recipes, and
routines for working with Python iterables.

              chunked, ichunked, chunked_even, sliced,
Grouping      constrained_batches, distribute, divide, split_at,
              split_before, split_after, split_into, split_when,
              bucket, unzip, batched, grouper, partition, transpose

Lookahead and spy, peekable, seekable
lookback

              windowed, substrings, substrings_indexes, stagger,

Getting started

To get started, install the library with pip:

pip install more-itertools

The recipes from the itertools docs are included in the top-level
package:

>>> from more_itertools import flatten
>>> iterable = [(0, 1), (2, 3)]
>>> list(flatten(iterable))
[0, 1, 2, 3]

Several new recipes are available as well:

>>> from more_itertools import chunked
>>> iterable = [0, 1, 2, 3, 4, 5, 6, 7, 8]
>>> list(chunked(iterable, 3))
[[0, 1, 2], [3, 4, 5], [6, 7, 8]]

>>> from more_itertools import spy
>>> iterable = (x * x for x in range(1, 6))
>>> head, iterable = spy(iterable, n=3)
>>> list(head)
[1, 4, 9]
>>> list(iterable)
[1, 4, 9, 16, 25]

For the full listing of functions, see the API documentation.
