I'm sorry, I'm new and not sure what to do about this and I certinally don't want to be "that guy" but:

This Kata has a "twin" ranked as a 5 kyu with python support only:

The (python) soulutions are all but portable (requiring only the swtich of the returns from failure or sucess messages to booleans).

I'm not sure what should be done about this, can they be merged? This kata appears to be older and supports more languages.

Is there some key difference or value I am missing for having what appear to be two very idential kata on different kyu levels?
