class_docstr: Returns the second tuple value in a list of LatLong tuples.
     For use with the LatLong logical type.
  
  Examples:
      >>> longitude = Longitude()
      >>> longitude([(42.4, -71.1),
      ...            (40.0, -122.4),
      ...            (41.2, -96.75)]).tolist()
      [-71.1, -122.4, -96.75]
code: def get_function(self):
      def longitude(latlong):
          latlong = np.array(latlong.tolist())
          return latlong[:, 1]
  
      return longitude
