docstring: Access a single value for a row/column label pair.
  
          Similar to ``loc``, in that both provide label-based lookups. Use
          ``at`` if you only need to get or set a single value in a DataFrame
          or Series.
  
          Raises
          ------
          KeyError
              If 'label' does not exist in DataFrame.
