Fredrik's advice is probably better, but if you must:

class Editor(object):
     table = {}
     def __new__(klass, name):
         try:
             return klass.table[name]
         except KeyError:
             klass.table[name] = super(Singled, klass).__new__(klass)
         return klass.table[name]
