objects and strings are immutable objects, and all python caches them efficiently, which leads us to think that Python should create new objects without the illusion of creating new objects. Python caches only simple integers, and the range of Python-cached integers changes, so don't use this feature. (I don't know ho

The path to python learning-simulate the LRU Algorithm in python Slicing,Problem description: A process just obtains the right to use three primary storage blocks. If the process accesses the page in the order of 1, 2, 3, 4, 2, 5, 5. When the LRU algorithm is used, what is the number of page missing times? Hint: LRU (Least Recently Used) indicates Least Recently
