# welcome to softhunt.net
# Python program explaining
# stack() function

import numpy as np

# input array
in_arr1 = np.array([1, 3, 5] )
print ("1st Input array : 
", in_arr1)

in_arr2 = np.array([2, 4, 6] )
print ("2nd Input array : 
", in_arr2)

# Stacking the two arrays along axis 0
out_arr1 = np.stack((in_arr1, in_arr2), axis = 0)
print ("Output stacked array along axis 0:
 ", out_arr1)

# Stacking the two arrays along axis 1
out_arr2 = np.stack((in_arr1, in_arr2), axis = 1)
print ("Output stacked array along axis 1:
 ", out_arr2)
