Returns the value for the kerning pair.
        **pair** is a ``tuple`` of two :ref:`type-string`\s, and the returned
        values will either be :ref:`type-int-float` or ``None``
        if no pair was found. ::

        It is important to understand that any changes to the returned value
        will not be reflected in the Kerning object. If one wants to make a change to
        the value, one should do the following::

            >>> value = font.kerning[("A", "V")]
            >>> value += 10
            >>> font.kerning[("A", "V")] = value
