n this chapter, we will discuss about NumPy – vsplit. This NumPy.vsplit is a special case of split() function where the axis is 1 indicating a vertical split regardless of the dimension of the input array. The following example makes this clear.

Example Of NumPy vsplit

import numpy as np 
a = np.arange(16).reshape(4,4) 

print 'First array:' 
print a 
print '\n'

print 'Vertical splitting:' 
b = np.vsplit(a,2) 
print b

Its output would be as follows −

First array:
[[ 0 1 2 3]
 [ 4 5 6 7]
 [ 8 9 10 11]
 [12 13 14 15]]

Vertical splitting:                                                           
[array([[0, 1, 2, 3],                                                         
       [4, 5, 6, 7]]), array([[ 8,  9, 10, 11],                               
       [12, 13, 14, 15]])]
