code: def construct_1d_object_array_from_listlike(values):
      
      # numpy will try to interpret nested lists as further dimensions, hence
      # making a 1D array that contains list-likes is a bit tricky:
      result = np.empty(len(values), dtype='object')
      result[:] = values
      return result

      dtype.

      Raises

      Returns
