这是我的嵌套元组列表...这意味着，每个元组在每个元组中包含另外两组元组。
R22 = [((13, 15, 1), (3, 8, 1)), ((13, 16, 1), (3, 11, 1)), ((13, 27, 1), (3, 32, 1)), ((13, 36, 1), (3, 44, 1)), ((13, 47, 1), (3, 46, 1)), ((15, 16, 1), (8, 11, 1)), ((15, 27, 1), (8, 32, 1)), ((15, 36, 1), (8, 44, 1)), ((15, 47, 1), (8, 46, 1)), ((16, 27, 1), (11, 32, 1)), ((16, 36, 1), (11, 44, 1)), ((16, 47, 1), (11, 46, 1)), ((27, 36, 1), (32, 44, 1)), ((27, 47, 1), (32, 46, 1)), ((36, 47, 1), (44, 46, 1))]
现在我需要找到部分元素的索引，例如
FindeIndex('13, 15') and the expected result would be 0,0 and for (3, 11) the answer would be 1,1. and for (3,8) the expected answer would be 0,1. and so on.
PS：请注意我并没有试图找到整个元组的索引，我只在NESTED元组中使用前两个PARTIAL元素。
And what i tried is
print(R22.index('(13, 27)')) is not working and saying can't find in list.
and i tried this way print(R22.index('(13, 27, 1), (3, 32, 1)')) also said not found.
