Here's a good function header given the following:
I wrote the below code

    path = hass.config.path(FOLDER)
    if (not os.path.isdir(path)):
        _LOGGER.warning('Folder    %s    not    found    in    config    folder', FOLDER)
        return False
    def python_script_service_handler(call):
        'Handle    python    script    service    calls.'
        execute_script(hass, call.service, call.data)
    for fil in glob.iglob(os.path.join(path, '*.py')):
        name = os.path.splitext(os.path.basename(fil))[0]
        hass.services.register(DOMAIN, name, python_script_service_handler)
    return True

What's a good function header?
