[<__main__.Num object at 0x100493450>, <__main__.Num object at 0x100493490>, <__main__.Num object at 0x1004934d0>, <__main__.Num object at 0x100493510>, <__main__.Num object at 0x100493550>, <__main__.Num object at 0x100493590>, <__main__.Num object at 0x1004935d0>, <__main__.Num object at 0x100493610>, <__main__.Num object at 0x100493650>, <__main__.Num object at 0x100493690>]
