def METHOD_NAME(src_crs, dst_crs, xs, ys):
    """Transform coordinates from one reference system to another.
    Parameters
    ----------
    src_crs: str or dict
        A string like 'EPSG:4326' or a dict of proj4 parameters like
        {'proj': 'lcc', 'lat_0': 18.0, 'lat_1': 18.0, 'lon_0': -77.0}
        representing the coordinate reference system on the "source"
        or "from" side of the transformation.
    dst_crs: str or dict
        A string or dict representing the coordinate reference system
        on the "destination" or "to" side of the transformation.
    xs: sequence of float
        A list or tuple of x coordinate values. Must have the same
        length as the ``ys`` parameter.
    ys: sequence of float
        A list or tuple of y coordinate values. Must have the same
        length as the ``xs`` parameter.
    Returns
    -------
    xp, yp: list of float
        A pair of transformed coordinate sequences. The elements of
        ``xp`` and ``yp`` correspond exactly to the elements of the
        ``xs`` and ``ys`` input parameters.
    Examples
    --------
    >>> transform('EPSG:4326', 'EPSG:26953', [-105.0], [40.0])
    ([957097.0952383667], [378940.8419189212])
