docs: r"""
      Initializes two :class:`~.wind_farm.WindFarm` objects.
  
      This function shows how to initialize a WindFarm object. You need to
      provide at least a name and a the wind farm's wind turbine fleet as done
      below for 'example_farm'. Optionally you can provide a wind farm efficiency
      (which can be constant or dependent on the wind speed) and coordinates as
      done for 'example_farm_2'. In this example the coordinates are not being
      used as just a single weather data set is provided as example data.
  
      Parameters
      ----------
      my_turbine : WindTurbine
          WindTurbine object with self provided power curve.
      e126 : WindTurbine
          WindTurbine object with power curve from data file provided by the
          windpowerlib.
  
      Returns
      -------
      Tuple (WindFarm, WindFarm)
