我有一个这样的熊猫数据框
start end compDepth compReleaseDepth compMeanRate
0 0.0 0.62 58.0999985 1.5 110
1 0.66 1.34 57.1399994 3 94
2 1.42 2.1 57.1399994 2.5 89
3 2.21 2.87 58.5699997 2.5 79
4 2.97 3.65 55.2399979 3.5 77
5 3.78 4.45 53.8600006 1.5 76
6 4.49 5.17 62.2700005 0.5 81
7 5.97 6.65 56.1899986 2.5 85
我需要将数据序列化为 JSON 并且我使用df.to_json(orient='records')
它并且它工作正常。
但是,我想将最后 3 列嵌套到一个名为"annotations"
. 这就是我想要实现的,有没有简单的方法可以做到这一点?
