Consolidation of existing third party recipes for partitioning of sets and multisets/bags.
Partition Sets provides a consolidated set of recipes gently provided by other users over the years and under the MIT license. I modified these slightly so that they now equally work under python2 and python3. All bugs are mine ;-)
You may find it useful for tasks involving small sets and also multi sets/bags.
Third party dependencies are documented in the folder third-party.
Feature requests and bug reports are best entered in the todos of partitionsets.
Primary Source repository∞
The main source of
partitionsets is on a mountain in central Switzerland.
We use distributed version control (git).
There is no central hub.
Every clone can become a new source for the benefit of all.
The preferred public clones of
- on codeberg - a democratic community-driven, non-profit software development platform operated by Codeberg e.V.
- at sourcehut - a collection of tools useful for software development.
