Python 中嵌套列表的嵌套元组中的两级排序

我有一个深度嵌套的嵌套列表元组，如下所示:

ip = (array([[[ 50,  73]],
       [[ 50, 107]],
       [[ 55, 108]],
       [[ 55, 121]],
       [[978,  87]],
       [[977,  86]],
       [[977,  73]]], dtype=int32), 

array([[[ 669,    3]],
       [[ 668,    4]],
       [[ 667,    4]],
       [[1033,   71]],
       [[1035,   69]],
       [[1035,    4]],
       [[ 848,    4]],
       [[ 847,    3]],
       [[ 813,    3]],
       [[ 718,    4]],
       [[ 717,    3]]], dtype=int32), 

array([[[ 17,   3]],
       [[ 16,   4]],
       [[  0,   4]],
       [[  0,  49]],
       [[197,  49]],
       [[197,   8]],
       [[ 84,   4]],
       [[ 83,   3]]], dtype=int32))

上面例子中的主要元组的长度是3.我想在上面的 struct 上加到perform a 2 level sorting.首先，我想要sort all the 3 elements in the main list in increasing order based on the first value of nested list.因此，在上面的例子中，third element将首先出现，因为它有第一个元素的lowest value，即0.第二个应该是first element，因为它有50的second lowest value，最后应该是third element，因为它有perform a 2 level sorting5的third lowest value.第一级排序的输出应为:

op = (array([[[ 17,   3]],
       [[ 16,   4]],
       [[  0,   4]],
       [[  0,  49]],
       [[197,  49]],
       [[197,   8]],
       [[ 84,   4]],
       [[ 83,   3]]], dtype=int32),

array([[[ 50,  73]],
       [[ 50, 107]],
       [[ 55, 108]],
       [[ 55, 121]],
       [[978,  87]],
       [[977,  86]],
       [[977,  73]]], dtype=int32), 

array([[[ 669,    3]],
       [[ 668,    4]],
       [[ 667,    4]],
       [[1033,   71]],
       [[1035,   69]],
       [[1035,    4]],
       [[ 848,    4]],
       [[ 847,    3]],
       [[ 813,    3]],
       [[ 718,    4]],
       [[ 717,    3]]], dtype=int32), 
)

现在，我想对上面的op再次执行相同的排序，但我不想对嵌套列表的第一个值进行排序，而是希望对嵌套列表的sort based on the second value进行排序.因此，现在的最终输出如下所示:

final_op = (array([[[ 17,   3]],
       [[ 16,   4]],
       [[  0,   4]],
       [[  0,  49]],
       [[197,  49]],
       [[197,   8]],
       [[ 84,   4]],
       [[ 83,   3]]], dtype=int32), 

array([[[ 669,    3]],
       [[ 668,    4]],
       [[ 667,    4]],
       [[1033,   71]],
       [[1035,   69]],
       [[1035,    4]],
       [[ 848,    4]],
       [[ 847,    3]],
       [[ 813,    3]],
       [[ 718,    4]],
       [[ 717,    3]]], dtype=int32),

array([[[ 50,  73]],
       [[ 50, 107]],
       [[ 55, 108]],
       [[ 55, 121]],
       [[978,  87]],
       [[977,  86]],
       [[977,  73]]], dtype=int32)
)

如有任何帮助，我们不胜感激！

提前谢谢！
