def dist_abs(self, src, tar, qval=<NUM_LIT:2>, normalized=False, alphabet=None):
return super(self.__class__, self).dist_abs(<EOL>src, tar, qval, <NUM_LIT:1>, normalized, alphabet<EOL>)<EOL>
Return the Manhattan distance between two strings.

        Parameters
        ----------
        src : str
            Source string (or QGrams/Counter objects) for comparison
        tar : str
            Target string (or QGrams/Counter objects) for comparison
        qval : int
            The length of each q-gram; 0 for non-q-gram version
        normalized : bool
            Normalizes to [0, 1] if True
        alphabet : collection or int
            The values or size of the alphabet

        Returns
        -------
        float
            The Manhattan distance

        Examples
        --------
        >>> cmp = Manhattan()
        >>> cmp.dist_abs('cat', 'hat')
        4.0
        >>> cmp.dist_abs('Niall', 'Neil')
        7.0
        >>> cmp.dist_abs('Colin', 'Cuilen')
        9.0
        >>> cmp.dist_abs('ATCG', 'TAGC')
        10.0
