more-itertools 2.1

More routines for operating on iterables, beyond itertools

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.

Version History

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.
