def transform(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])
