Python でこんな処理を書いたことはありませんか? 同じ引数で何度も呼ばれる関数 API や DB に何回も同じ問い合わせをしている 再帰処理がやたら遅い こういう場面で即効性があるのが functools.lru_cache(キャッシュ) です。 数行追加するだけで、処理時間が ...
Python trades runtime speed for programmer convenience, and most of the time it’s a good tradeoff. One doesn’t typically need the raw speed of C for most workaday applications. And when you need to ...
Once decorated, the callable will inherit the functionality of safecache and begin safely caching returned results. Caching using native Python can be useful to minimize the caching latency (e.g.
LRUCache(int capacity) Initialize the LRU cache with positive size capacity. int get(int key) Return the value of the key if the key exists, otherwise return -1. void put(int key, int value) Update ...
