np.array indexing code example
Example 1: indexing a numpy array in python
array = [[0 1 2 3 4 5]
[6 7 8 9 10 11]
[12 13 14 15 16 17]
[18 19 20 21 22 23]
[24 25 26 27 28 29]
[30 31 32 33 34 35]]
array[0, 3:5] = [3 4]
array[4:, 4:] = [[28 29],
[34 35]]
array[:, 2] = [2 8 14 20 26 32]
array[2:;2, ::2] = [[12 14 16],
[24 26 28]]
Example 2: numpy indexing
>>> x = np.array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9])
>>> x[1:7:2]
array([1, 3, 5])
