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.

Getting started
===============
To get started, install the library with `pip `_:
.. code-block:: shell
pip install more-itertools
The recipes from the `itertools docs `_
are included in the top-level package:
.. code-block:: python
>>> from more_itertools import flatten
>>> iterable = [(0, 1), (2, 3)]
>>> list(flatten(iterable))
[0, 1, 2, 3]
Several new recipes are available as well:
.. code-block:: python
>>> 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 `_.
