numpy.record.newbyteorder
- 
record.newbyteorder(new_order='S')
- 
Return a new dtypewith a different byte order.Changes are also made in all fields and sub-arrays of the data type. The new_ordercode can be any from the following:- ‘S’ - swap dtype from current to opposite endian
- {‘<’, ‘L’} - little endian
- {‘>’, ‘B’} - big endian
- {‘=’, ‘N’} - native order
- {‘|’, ‘I’} - ignore (no change to byte order)
 Parameters: new_order : str, optional Byte order to force; a value from the byte order specifications above. The default value (‘S’) results in swapping the current byte order. The code does a case-insensitive check on the first letter of new_orderfor the alternatives above. For example, any of ‘B’ or ‘b’ or ‘biggish’ are valid to specify big-endian.Returns: new_dtype : dtype New dtypeobject with the given change to the byte order.
