code: def shortest_line(a, b, **kwargs):
      """
      Returns the shortest line between two geometries.
  
      The resulting line consists of two points, representing the nearest
      points between the geometry pair. The line always starts in the first
      geometry `a` and ends in he second geometry `b`. The endpoints of the
      line will not necessarily be existing vertices of the input geometries
      `a` and `b`, but can also be a point along a line segment.
  
      Parameters
      ----------
      a : Geometry or array_like
      b : Geometry or array_like
      **kwargs
          See :ref:`NumPy ufunc docs <ufuncs.kwargs>` for other keyword arguments.
  
      See also
      --------
      prepare : improve performance by preparing ``a`` (the first argument) (for GEOS>=3.9)
  
      Examples
      --------
