numpy.dtype.byteorder#
attribute
- dtype.byteorder#
A character indicating the byte-order of this data-type object.
One of:
‘=’
native
‘<’
little-endian
‘>’
big-endian
‘|’
not applicable
All built-in data-type objects have byteorder either ‘=’ or ‘|’.
Examples
>>> dt = np.dtype('i2') >>> dt.byteorder '=' >>> # endian is not relevant for 8 bit numbers >>> np.dtype('i1').byteorder '|' >>> # or ASCII strings >>> np.dtype('S2').byteorder '|' >>> # Even if specific code is given, and it is native >>> # '=' is the byteorder >>> import sys >>> sys_is_le = sys.byteorder == 'little' >>> native_code = '<' if sys_is_le else '>' >>> swapped_code = '>' if sys_is_le else '<' >>> dt = np.dtype(native_code + 'i2') >>> dt.byteorder '=' >>> # Swapped code shows up as itself >>> dt = np.dtype(swapped_code + 'i2') >>> dt.byteorder == swapped_code True
