Review Summary

Your cache decorator implementation is complete and working correctly. It properly stores and retrieves cached results, handles variable arguments with *args and **kwargs, maintains separate caches for each decorated function, and prints the appropriate messages ("Getting from cache" and "Calculating new result"). The code follows Python conventions with descriptive variable names and consistent double quotes as required by the style guidelines. All functional requirements from the task have been met.
