Class KeyedSets

source code

This is a collection of named sets. In principal, it contains an empty set for every name, and you can add things to sets, discard things from sets, and so on.

>>> ks = KeyedSets()
>>> ks['tim']                   # get a named set
>>> ks.add('tim', 'friendly')   # add an element to a set
>>> ks.add('tim', 'dexterous')
>>> ks['tim']
set(['friendly', 'dexterous'])
>>> 'tim' in ks                 # membership testing
>>> 'ron' in ks
>>> ks.discard('tim', 'friendly')# discard set element
>>> ks.pop('tim')               # return set and reset to empty
>>> ks['tim']

This class is careful to conserve memory space - empty sets do not occupy any space.
