[已解决]求助一下，如何切割按照范围切割数组，还有下图这种问题可以怎么解决>_<

MeltryllisEgo

部分代码如下
cloud1 = np.asarray(ply1.points)
print(cloud1, type(cloud1), len(cloud1))
#按照x轴的中值切割点云
a = cloud1[np.any(cloud1 < xyz_half1, axis=0)]

arr = ['a', 'b', 'c', 'd', 'e']

a = arr[2:4]
b = arr[:3]
c = arr[2:]
d = arr[::-1]
e = arr[::2]
f = arr[-3]

print(a)
print(b)
print(c)
print(d)
print(e)
print(f)

输出结果：

['c', 'd']
['a', 'b', 'c']
['c', 'd', 'e']
['e', 'd', 'c', 'b', 'a']
['a', 'c', 'e']
c
