esets 0.1.0

Extended sets

eset

Extended sets - support for set complement

Overview

An eset works like a normal python set except that you can invert it to generate its complement. For example, let's say you have the following:

>>> from eset import eset
>>> s = eset(['hello'. 'there'])
>>> s_invert = ~s
>>> s_invert
~eset(['hello', 'there'])

In this example, s_invert contains everything except 'hello' and 'there'.

Logic

All the logic operations you'd expect from sets are available in esets, including intersection, union, difference, and symmetric difference. Use the &, |, -, and ^ operators respectively.

Similarly, conditional expressions are available to determine subset relationships. If A <= B, that A is a subset of B.
