select every last row from numpy multidimensional array code example

Example 1: python how to copy a 2d array leaving out last column

In [1]: import numpy as np

In [2]: H = np.meshgrid(np.arange(5), np.arange(5))[0]

In [3]: H
Out[3]: 
array([[0, 1, 2, 3, 4],
       [0, 1, 2, 3, 4],
       [0, 1, 2, 3, 4],
       [0, 1, 2, 3, 4],
       [0, 1, 2, 3, 4]])

In [4]: Hsub = H[1:-1,1:-1]

In [5]: Hsub
Out[5]: 
array([[1, 2, 3],
       [1, 2, 3],
       [1, 2, 3]])

Example 2: How to select parts of a numpy array

import numpy as np

x = np.array([1,2,4,3,5,1,4,2])#create an array...

x[n]#where n is any value from the size of the array 
	#e.g. x[1] is 2, x[5] is 1.
