More routines for operating on iterables, beyond itertools

Project description

I love itertools; it’s one of the most beautiful, composable standard libs. Whenever I have an iteration problem, there’s almost always an itertools routine that fits it perfectly. Sometimes, however, neither itertools nor the recipes included in its docs do quite what I need.

Here I’ve collected several routines I’ve reached for but not found. Since they are deceptively tricky to get right, I’ve wrapped them up into a library. We’ve also included implementations of the recipes from the itertools documentation. Enjoy! Any additions are welcome; just file a pull request.

Please see http://packages.python.org/more-itertools/api.html for the list of routines.

Version History

2.2
  • Added iterate and with_iter. (Thanks, abarnert!)
2.1
  • Added (tested!) implementations of the recipes from the itertools documentation. (Thanks, Chris Lonnen!)
  • Added ilen. (Thanks for the inspiration, Matt Basta!)
2.0
  • chunked now returns lists rather than tuples. After all, they’re homogeneous. This slightly backward-incompatible change is the reason for the major version bump.
  • Added @consumer.
  • Improved test machinery.
1.1
  • Added first function.
  • Added Python 3 support.
  • Added a default arg to peekable.peek().
  • Noted how to easily test whether a peekable iterator is exhausted.
  • Rewrote documentation.
1.0
  • Initial release, with collate, peekable, and chunked. Could really use better docs.
