collections_extended documentation

collections_extended is a pure Python module with no dependencies providing

  • a bag class, AKA multiset,

  • a setlist class, which is a unique list or ordered set,

  • a bijection class,

There are also frozen (hashable) varieties of bags and setlists.

It is tested against CPython 3.6, 3.7, 3.8, 3.9, 3.10, PyPy3.6, PyPy3.7, & PyPy3.8. The current version no longer supports Python 2, install a 1.x version for a Python 2.7 compatible version. New features will not be developed but serious bugs may be fixed.
