问在Python中，如何获取数组中均匀分布的多个不相邻的行或列？

EN

import numpy as np

simple_array = np.arange(6)
print(simple_array)

# array[startIndex : endIndex : stepValue]*
print(simple_array[1:5:2])

# if you want to include the last value, you need to go above it
print(simple_array[1:6:2])

# obtain the first n-elements using array[:n]. Note that the n-th element isn't included
print(simple_array[:4])

# or the elements after that with array[n:]. Note that the n-th element is included
print(simple_array[4:])

# use step value with array[::n]
print(simple_array[::2])

# this will return the columns 3-5, with 5 not being included
print(simple_array[3:5])

# here we start at column 1, with a step of 2
print(simple_array[1::2])

[0, 1, 2, 3, 4, 5]
[1, 3]
[1, 3, 5]
[0, 1, 2, 3]
[4, 5]
[0, 2, 4]
[3, 4]
[1, 3, 5]
