ndarray.argsort(axis=-1, kind='quicksort', order=None) Returns the indices that would sort this array. Refer to

ndarray.dumps() Returns the pickle of the array as a string. pickle.loads or numpy.loads will convert the string back to

numpy.mintypecode(typechars, typeset='GDFgdf', default='d')

numpy.core.records.fromfile(fd, dtype=None, shape=None, offset=0, formats=None, names=None, titles=None, aligned=False, byteorder=None)

generic.real real part of scalar

numpy.core.defchararray.count(a, sub, start=0, end=None)

chararray.view(dtype=None, type=None) New view of array with the same data.

matrix.newbyteorder(new_order='S') Return the array with the same data viewed with a different byte order. Equivalent

recarray.flatten(order='C') Return a copy of the array collapsed into one dimension.

recarray.nbytes Total bytes consumed by the elements of the array. Notes Does not include
