    mylisy=[1,2,3,4,5]
    arr=np.array(mylisy)
    arr=np.array(mylisy)
    –>o/p:-(5,) means 5 columns 0 rows[first column ,second rows]
    where as
    myarray1=[1,2,3,4]

    myarray2=[5,6,7,8]

    myarray3=[9,8,7,6]
    arr2=np.array([myarray1,myarray2,myarray3])

    arr2.shape
    –>o/p:-(3, 4) here first rows (3) and then 4 (column)
    why both time o/p not same ? it should be (row, column )or (column , row )
