Considering the following dataset:

>>> data[:10]
array([('T',  2,  8,  3, 5, 1,  8, 13, 0, 6,  6, 10,  8, 0,  8, 0,  8),('I',  5, 12,  3, 7, 2, 10,  5, 5, 4, 13,  3,  9, 2,  8, 4, 10),('D',  4, 11,  6, 8, 6, 10,  6, 2, 6, 10,  3,  7, 3,  7, 3,  9),('N',  7, 11,  6, 6, 3,  5,  9, 4, 6,  4,  4, 10, 6, 10, 2,  8),('G',  2,  1,  3, 1, 1,  8,  6, 6, 6,  6,  5,  9, 1,  7, 5, 10),('S',  4, 11,  5, 8, 3,  8,  8, 6, 9,  5,  6,  6, 0,  8, 9,  7),('B',  4,  2,  5, 4, 4,  8,  7, 6, 6,  7,  6,  6, 2,  8, 7, 10),('A',  1,  1,  3, 2, 1,  8,  2, 2, 2,  8,  2,  8, 1,  6, 2,  7),('J',  2,  2,  4, 4, 2, 10,  6, 2, 6, 12,  4,  8, 1,  6, 1,  7),('M', 11, 15, 13, 9, 7, 13,  2, 6, 2, 12,  1,  9, 8,  1, 1,  8)], dtype=[('f0', 'S1'), ('f1', '<i8'), ('f2', '<i8'), ('f3', '<i8'), ('f4', '<i8'), ('f5', '<i8'), ('f6', '<i8'), ('f7', '<i8'), ('f8', '<i8'), ('f9', '<i8'), ('f10', '<i8'), ('f11', '<i8'), ('f12', '<i8'), ('f13', '<i8'), ('f14', '<i8'), ('f15', '<i8'), ('f16', '<i8')])

How one can access all elements except the first one from each array. I am using the following code but to no avail.

>>> nd.array([[x[1:] for x in data[:10]])

Any help is really appreciated.

You can access all column names with the dtype.names attribute and then slice it:

>>> data[list(data.dtype.names[1:])]
array([( 2,  8,  3, 5, 1,  8, 13, 0, 6,  6, 10,  8, 0,  8, 0,  8),( 5, 12,  3, 7, 2, 10,  5, 5, 4, 13,  3,  9, 2,  8, 4, 10),( 4, 11,  6, 8, 6, 10,  6, 2, 6, 10,  3,  7, 3,  7, 3,  9),( 7, 11,  6, 6, 3,  5,  9, 4, 6,  4,  4, 10, 6, 10, 2,  8),( 2,  1,  3, 1, 1,  8,  6, 6, 6,  6,  5,  9, 1,  7, 5, 10),( 4, 11,  5, 8, 3,  8,  8, 6, 9,  5,  6,  6, 0,  8, 9,  7),( 4,  2,  5, 4, 4,  8,  7, 6, 6,  7,  6,  6, 2,  8, 7, 10),( 1,  1,  3, 2, 1,  8,  2, 2, 2,  8,  2,  8, 1,  6, 2,  7),( 2,  2,  4, 4, 2, 10,  6, 2, 6, 12,  4,  8, 1,  6, 1,  7),(11, 15, 13, 9, 7, 13,  2, 6, 2, 12,  1,  9, 8,  1, 1,  8)],dtype=[('f1', '<i8'), ('f2', '<i8'), ('f3', '<i8'), ('f4', '<i8'), ('f5', '<i8'), ('f6', '<i8'), ('f7', '<i8'), ('f8', '<i8'),('f9', '<i8'), ('f10', '<i8'), ('f11', '<i8'), ('f12', '<i8'), ('f13', '<i8'), ('f14', '<i8'), ('f15', '<i8'), ('f16', '<i8')])
