numpy randomly swap lines

>>> X = np.random.random((6, 2))
>>> X
array([[ 0.9818058 ,  0.67513579],
       [ 0.82312674,  0.82768118],
       [ 0.29468324,  0.59305925],
       [ 0.25731731,  0.16676408],
       [ 0.27402974,  0.55215778],
       [ 0.44323485,  0.78779887]])

>>> np.random.shuffle(X)
>>> X
array([[ 0.9818058 ,  0.67513579],
       [ 0.44323485,  0.78779887],
       [ 0.82312674,  0.82768118],
       [ 0.29468324,  0.59305925],
       [ 0.25731731,  0.16676408],
       [ 0.27402974,  0.55215778]])

Here is what the above code is Doing:
1. We create a random array of size 6×2.
2. We shuffle the array.
3. We print the shuffled array.
