Solve the following python programming problem given the following code:
@ property 
def key(self) : 
    accessors = [] 
    reversing = [] 
    for order_by in order_by : 
        accessors.append (Accessor (order_by.bare)) 
        reversing.append (order_by.is_descending) 
@ total_ordering 
    class Comparator (object) : 
        def __init__(self, obj) : 
            self.obj = obj 
def __eq__(self, other) : 
            for accessor in accessors : 
                a = accessor.resolve (self.obj, quiet = True) 
                b = accessor.resolve (other.obj, quiet = True) 
                if (not (a == b)) : 
                    return False 
return True 
def __lt__(self, other) : 
            for (accessor, reverse) in six.moves.zip (accessors, reversing) : 
                a = accessor.resolve (self.obj, quiet = True) 
                b = accessor.resolve (other.obj, quiet = True) 
                if (a == b) : 
                    continue 
if reverse : 
                    (a, b) = (b, a)

                    return (a < b)
