Review Summary

The implementation is working correctly and meets all requirements. The cache decorator properly stores results for different arguments, returns cached values without re-executing the function, prints the correct messages (Getting from cache and Calculating new result), and each decorated function maintains its own separate cache through closure scoping. The only issue noted is a minor inefficiency where if args in main_cache.keys() calls .keys() unnecessarily when if args in main_cache would work identically. This has no functional impact since dictionary lookups are O(1) either way, but you could simplify it to if args in main_cache for cleaner code. All checklist items pass, and your solution demonstrates good understanding of decorators, closures, and caching logic. Great work!
