code: def unpackbits(myarray, axis=None):
      """
      unpackbits(myarray, axis=None)
  
      Unpacks elements of a uint8 array into a binary-valued output array.
  
      Each element of `myarray` represents a bit-field that should be unpacked
      into a binary-valued output array. The shape of the output array is either
      1-D (if `axis` is None) or the same shape as the input array with unpacking
      done along the axis specified.
  
      Parameters
      ----------
      myarray : ndarray, uint8 type
         Input array.
      axis : int, optional
          The dimension over which bit-unpacking is done.
          ``None`` implies unpacking the flattened array.
  
      Returns
      -------
      unpacked : ndarray, uint8 type
         The elements are binary-valued (0 or 1).
  
      See Also
      --------
      packbits : Packs the elements of a binary-valued array into bits in a uint8
                 array.
  
      Examples
      --------
      >>> a = np.array([[2], [7], [23]], dtype=np.uint8)
      >>> a
      array([[ 2],
             [ 7],
             [23]], dtype=uint8)
      >>> b = np.unpackbits(a, axis=1)
      >>> b
      array([[0, 0, 0, 0, 0, 0, 1, 0],
             [0, 0, 0, 0, 0, 1, 1, 1],
             [0, 0, 0, 1, 0, 1, 1, 1]], dtype=uint8)
