[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)]

1. arr = ['a', 'b', 'c', 'd', 'e']
   
2. 
   
3. a = arr[2:4]
   
4. b = arr[:3]
   
5. c = arr[2:]
   
6. d = arr[::-1]
   
7. e = arr[::2]
   
8. f = arr[-3]
   
9. 
   
10. print(a)
    
11. print(b)
    
12. print(c)
    
13. print(d)
    
14. print(e)
    
15. print(f)

输出结果：

1. ['c', 'd']
   
2. ['a', 'b', 'c']
   
3. ['c', 'd', 'e']
   
4. ['e', 'd', 'c', 'b', 'a']
   
5. ['a', 'c', 'e']
   
6. c
