"Use % formatting in logging functions and pass the % parameters as
Can anybody give a judgement on this? If the .format is preferred,
then we'll look into changing the landscape.io settings.
As far as I can tell from the Python 2 logging docs  at least, the
following is indeed the preferred approach:
logging.info("Some message with a param: %s", param)
One of the reasons is that the string representation of param does not
need to be evaluated if the framework can determine that info logging is
not enabled - this differs from using format, where the string has to be
calculated irrespective of whether it is ever emitted.
