Solve the following python programming problem given the following code:
def __init__(self, w, align = LEFT, width = RELATIVE_100, min_width = None, left = 0, right = 0) : 
    '
        :param w: a box, flow or fixed widget to pad on the left and/or right
            this widget is stored as self.original_widget
        :type w: Widget

        :param align: one of: ``\'left\'``, ``\'center\'``, ``\'right\'``
            (``\'relative\'``, *percentage* 0=left 100=right)

        :param width: one of:

            *given width*
              integer number of columns for self.original_widget

            ``\'pack\'``
              try to pack self.original_widget to its ideal size

            (``\'relative\'``, *percentage of total width*)
              make width depend on the container\'s width

            ``\'clip\'``
              to enable clipping mode for a fixed widget

        :param min_width: the minimum number of columns for
            self.original_widget or ``None``
        :type min_width: int

        :param left: a fixed number of columns to pad on the left
        :type left: int

        :param right: a fixed number of columns to pad on the right
        :type right: int

        Clipping Mode: (width= ``\'clip\'``)
        In clipping mode this padding widget will behave as a flow
        widget and self.original_widget will be treated as a fixed
        widget.  self.original_widget will will be clipped to fit
        the available number of columns.  For example if align is
        ``\'left\'`` then self.original_widget may be clipped on the right.

        >>> size = (7,)
        >>> def pr(w):
        ...     for t in w.render(size).text:
        ...         print "|%s|" % (t.decode(\'ascii\'),)
        >>> pr(Padding(Text(u"Head"), (\'relative\', 20), \'pack\'))
        | Head  |
        >>> pr(Padding(Divider(u"-"), left=2, right=1))
        |  ---- |
        >>> pr(Padding(Divider(u"*"), \'center\', 3))
        |  ***  |
        >>> p=Padding(Text(u"1234"), \'left\', 2, None, 1, 1)
        >>> p
        <Padding flow widget <Text flow widget...

    
    

    Fix the buggy line: (self._width_type, self._width_amount) = normalize_width (w, PaddingError)
