To better adhere to the Single-Responsibility Principle (SRP) from SOLID design principles, it's preferable to implement the "doubly linked list" and the "LRU Cache" as separate classes, with the linked list used inside LruCache to manage ordering.

You could copy your linked_list.py to this folder.

Alternatively, use a suitable Python built-in class.

Could you update your code using one of these approaches?

Thanks, I copy Linked_list.py to this folder and update two files, Hopefully you are happy with it.
