More Itertools

Python'sitertools library is a gem - you can compose elegant solutionsfor a variety of problems with the functions it provides. Inmore-itertoolswe collect additional building blocks, recipes, and routines for working withPython iterables.

Getting started

To get started, install the library withpip:

pip install more-itertools

The recipes from theitertools docsare included in the top-level package:

>>>frommore_itertoolsimportflatten>>>iterable= [(0,1), (2,3)]>>>list(flatten(iterable))[0,1,2,3]

Several new recipes are available as well:

>>>frommore_itertoolsimportchunked>>>iterable= [0,1,2,3,4,5,6,7,8]>>>list(chunked(iterable,3))[[0,1,2], [3,4,5], [6,7,8]]>>>frommore_itertoolsimportspy>>>iterable= (x*xforxinrange(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 theAPI documentation.
