HackerRank Python Solution - Numpy Topic - Concatenate

Concatenate:

Two or more arrays can be concatenated together using the concatenate function with a tuple of the arrays to be joined:

import numpy

array_1 = numpy.array([1,2,3])
array_2 = numpy.array([4,5,6])
array_3 = numpy.array([7,8,9])

print numpy.concatenate((array_1, array_2, array_3))    

#Output
[1 2 3 4 5 6 7 8 9]

Library List in AS400

Library List: 

• A library list is a list of libraries maintained for each user session with the libraries arranged in decreasing order of priority.
