If you're running this code standalone, it will insert the directory one level up from the current working directory (..) as the first item in the Python path, so that subsequent imports will look there first. If you're calling this code from another script, it can't rely on knowing the current working directory - so it calls os.path.split to find the directory where this file is located; then it inserts the parent of that directory as the first item in the Python path.
