Concatenate

    Python 3: Below code works fine: import numpy

    N, M, P = map(int, input().split())

NP = numpy.array([input().split() for i in range(N)], int)
MP = numpy.array([input().split() for j in range(M)], int)

print(numpy.concatenate((NP, MP), axis = 0))

    Why is that writing the code in below fashion gives addresses and not the expected result?

    import numpy

N, M, P = map(int, input().split())

NP = numpy.array([map(int, input().split()) for i in range(N)])
MP = numpy.array([map(int, input().split()) for j in range(M)])

print(numpy.concatenate((NP, MP), axis = 0))

    Solution to above: 

    [<map object at 0x7f4a5171d1d0> <map object at 0x7f4a516eb2b0>
<map object at 0x7f4a516eb2e8> <map object at 0x7f4a516f0780>
<map object at 0x7f4a516f0710> <map object at 0x7f4a49972da0>
<map object at 0x7f4a4946d390>]
