lru_cache是Python标准库functools中的一个函数装饰器,用于缓存函数的结果。当被装饰的函数再次被调用时,如果其参数与之前某次调用完全相同,则直接从缓存中返回结果,而不是重新执行函数体。这样可以显著提高程序的执行效率,特别是对于那些计算成本较高或IO密集型的函数。lru_cache使用最近最少使用(Least Recently Used,...

很多时候你只想要导入一个模块或库中的某个部分。我们来看看在Python中如何实现这点:from functools import lru_cache 上面这行代码可以让你直接调用lru_cache。如果你按常规方式导入functools,那么你就必须像这样调用lru_cache:functools.lru_cache(*args) 根据你实际的使用场景,上面的做法可能是更好的。在复杂的代码...
