在numpy数组Python中提取列的特定RANGE

我有一个数组:

e = np.array([[ 0,  1,  2,  3, 5, 6, 7, 8],
              [ 4,  5,  6,  7, 5, 3, 2, 5],
              [ 8,  9, 10, 11, 4, 5, 3, 5]])

我想通过RANGE中的列提取数组,如果我想在范围1到5之间取列,它将返回

e = np.array([[ 1,  2,  3, 5, ],
              [ 5,  6,  7, 5, ],
              [ 9, 10, 11, 4, ]])

怎么解决？谢谢

您可以使用e [:,1:5]来检索您想要的内容.

In [1]: import numpy as np

In [2]: e = np.array([[ 0,  1,  2,  3, 5, 6, 7, 8],
   ...:               [ 4,  5,  6,  7, 5, 3, 2, 5],
   ...:               [ 8,  9, 10, 11, 4, 5, 3, 5]])

In [3]: e[:, 1:5]
Out[3]:
array([[ 1,  2,  3,  5],
       [ 5,  6,  7,  5],
       [ 9, 10, 11,  4]])
