Description is not clear about default parameter and python function name does not follow PEP 8 naming recommendation, which is not good, considering 8kyu kata is excercise mainly for beginers.

IMHO needs more precise definition of what data should be collected. For example: i have to look at the tests to find out that first parameters are ignored in args and classes are represented by actual object, not by name. There is also not clear whether log getters/setters. Anyway nice kata :-)
