Ordered Set.

## oset

Set that remembers original insertion order.

Runs on Py2.5 or later (and runs on 3.0 or later without any modifications). For Python2.5, a local backport of ABC classes is also used.

Implementation based on a doubly linked link and an internal dictionary. This design gives OrderedSet the same big-Oh running times as regular sets including O(1) adds, removes, and lookups as well as O(n) iteration.

### Usage

Import and create ordered set.

>>> from oset import oset
>>> os = oset()


• Python 2.5+
