请教如何拆分数组

[songdg]

array([[135501,40], [135515, 10], [135545,20],[135553,30], [135558, 50], [135605,40], [135625, 18], [135655,60],[135659,10], [135700,70], [135705, 90, [135713,60],[135723,30], [135738, 20],[135745, 90, [135749,60],[135752,30], [135757, 20],[135758, 50]])
数组的第一列为时间（时分秒），我想根据分钟把数组拆分成几个数组。

数组好好的，干嘛要拆他

[ruoyu0088]

import numpy as np

#a = ...

loc = np.where(np.diff(a[:, 0] // 100))[0] + 1

for arr in np.split(a, loc):

print(arr)
