How can I get a column from a 2D python array?

Question

I want to know the co

import numpy as np
a = np.array([[0,0,0,2,3,0],[3,2,4,0,0,1]])

If I want to get col2 to col4, so result may be:

[[0,2,3][4,0,0]]

How can I make it? Thanks.

I think that here there is almost all you need about numpy slicing — Francesco Montesano

Besides: your title and your question don't match. Fix either one or the other — Francesco Montesano

>>> import numpy as np
>>> a = np.array([[0,0,0,2,3,0],[3,2,4,0,0,1]])
>>> a[:,2:5]
array([[0, 2, 3],
       [4, 0, 0]])
