Limitations: Cache implementations are not inherited from inerface or base class. Output: Time taken to execute the function without lru_cache is 0.4448213577270508 Time taken to execute the function with lru_cache is 2.8371810913085938e-05 This website uses cookies and other tracking technology to analyse traffic, personalise ads and learn how we can improve the experience for our visitors and customers. - Remove ``self`` from ``cachedmethod`` key arguments (breaking change).
