Solve the following python programming problem given the following code:
def choose_dark_palette(input = 'husl', as_cmap = False) : 
    "Launch an interactive widget to create a dark sequential palette.

    This corresponds with the :func:`dark_palette` function. This kind
    of palette is good for data that range between relatively uninteresting
    low values and interesting high values.

    Requires IPython 2+ and must be used in the notebook.

    Parameters
    ----------
    input : {'husl', 'hls', 'rgb'}
        Color space for defining the seed value. Note that the default is
        different than the default input for :func:`dark_palette`.
    as_cmap : bool
        If True, the return value is a matplotlib colormap rather than a
        list of discrete colors.

    Returns
    -------
    pal or cmap : list of colors or matplotlib colormap
        Object that can be passed to plotting functions.

    --------
    dark_palette : Create a sequential palette with dark low values.
    light_palette : Create a sequential palette with bright low values.
