  11. def formatPath(path: String, testWindows: Boolean = false): String

    Format the python file path so that it can be added to the PYTHONPATH correctly.

    Format the python file path so that it can be added to the PYTHONPATH correctly.

    Python does not understand URI schemes in paths. Before adding python files to the PYTHONPATH, we need to extract the path from the URI. This is safe to do because we currently only support local python files.

  12. def formatPaths(paths: String, testWindows: Boolean = false): Array[String]

    Format each python file path in the comma-delimited list of paths, so it can be added to the PYTHONPATH correctly.
