Parameters ---------- code : str The code to convert. It is converted to lower case before parsing. Legal values are: 'little', 'big', 'l', 'b', 'le', 'be', '<', '>', 'native', '=', 'swapped', 's'. Returns ------- out_code : {'<', '>'} Here '<' is the numpy dtype code for little endian, and '>' is the code for big endian. Examples -------- >>> import sys >>> sys_is_le == (sys.byteorder == 'little') True >>> to_numpy_code('big') '>' >>> to_numpy_code('little') '<' >>> nc = to_numpy_code('native') >>> nc == '<' if sys_is_le else nc == '>' True >>> sc = to_numpy_code('swapped') >>> sc == '>' if sys_is_le else sc == '<' True Nrrrrr r zWe cannot handle byte order %s)ÚlowerÚ native_codeÚaliasesÚ swapped_codeÚ ValueError)Úcode©rúR/var/www/html/virt/lib64/python3.6/site-packages/scipy/io/matlab/byteordercodes.pyÚ to_numpy_codes#    r)rrrr)rrrr )r r )r r )Ú__doc__ÚsysÚ byteorderZ sys_is_lerrrrrrrrÚs
