The best solution would be to change every call to sets.Set() to set(), 
and change the line:

import sets

to this:

except NameError:
    from sets import Set as set

If you use sets.ImmutableSet, you will need to change that to frozenset 
in the same way.

This assumes you don't need to support older versions of Python, before 
set() became a built-in.
