# pandas.Index.byteswap

`Index.``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')
