 To check this was done properly, you can open a DOS console (`CMD.EXE`) and type `python --version`.
 If it displays the correct Python version, then, everything is setup properly and you should be able to run the Python example provided with Webots in the `WEBOTS_HOME/projects/languages/python/worlds/example.wbt` world file.
