numpy.ndarray.byteswap — NumPy v1.11 Manual (original) (raw)
ndarray.byteswap(inplace)¶
Swap the bytes of the array elements
Toggle between low-endian and big-endian data representation by returning a byteswapped array, optionally swapped in-place.
| Parameters: | inplace : bool, optional If True, swap bytes in-place, default is False. |
|---|---|
| Returns: | out : ndarray The byteswapped array. If inplace is True, this is a view to self. |
Examples
A = np.array([1, 256, 8755], dtype=np.int16) map(hex, A) ['0x1', '0x100', '0x2233'] A.byteswap(True) array([ 256, 1, 13090], dtype=int16) map(hex, A) ['0x100', '0x1', '0x3322']
Arrays of strings are not swapped
A = np.array(['ceg', 'fac']) A.byteswap() array(['ceg', 'fac'], dtype='|S3')
