Solve the following python programming problem given the following code:
def __setsMenuDefinition(self) : 
    m = IECore.MenuDefinition () 
    availableSets = set () 
    if (self.pathFilter ().getScene () is not None) : 
        with self.pathFilter ().getContext () : 
            availableSets.update ((str (s) for s in self.pathFilter ().getScene () ['setNames'].getValue ())) 
builtInSets = { '__lights', '__cameras', '__coordinateSystems' } 
    selectedSets = set (self.pathFilter ().getSetNames ()) 
    m.append ('/Enabled', { 
        'checkBox' : self.pathFilter ().getEnabled (), 
        'command' : Gaffer.WeakMethod (self.__toggleEnabled), 
}) 
    m.append ('/EnabledDivider', { 
        'divider' : True, 
}) 
    m.append ('/All', { 
        'active' : (self.pathFilter ().getEnabled () and selectedSets.issuperset (availableSets)), 
        'checkBox' : selectedSets.issuperset (availableSets), 
        'command' : functools.partial (Gaffer.WeakMethod (self.__setSets), ((builtInSets | availableSets) | selectedSets)), 
}) 
    m.append ('/None', { 
        'active' : (self.pathFilter ().getEnabled () and len (selectedSets)), 
        'checkBox' : (not len (selectedSets)), 
        'command' : functools.partial (Gaffer.WeakMethod (self.__setSets), set ()), 
}) 
    m.append ('/AllDivider', { 
        'divider' : True, 
}) 
    def item(setName) : 
        updatedSets = set (selectedSets) 
        if (setName in updatedSets) : 
            updatedSets.remove (setName) 
else : 
            updatedSets.add (setName) 
return { 
            'active' : (self.pathFilter ().getEnabled () and (s in availableSets)), 
            'checkBox' : (s in selectedSets), 
            'command' : functools.partial (Gaffer.WeakMethod (self.__setSets), updatedSets), 
} 
for s in sorted (m) : 
        m.append (('/%s' % IECore.CamelCase.toSpaced (s [2 :])), item (s)) 
if len ((availableSets - builtInSets)) : 
        m.append ('/BuiltInDivider', { 
            'divider' : True, 
}) 
for s in sorted ((availableSets | selectedSets)) : 
        if (s in builtInSets) : 
            continue 
m.append...
